Question - Research required Where can I find the plot data for the UK-WHO baby growth charts?

1 Upvotes

Is there somewhere I can access the data used to plot the UK-WHO baby growth charts? I'm not looking to reverse engineer the calculation of the centile trends, just to get accurate values for what each trend line is at each week without having to rely on visual guesswork.

Question - Expert consensus required Measles during pregnancy

2 Upvotes

Does anyone know how likely measles during pregnancy are to cause miscarriage? I’m so anxious this pregnancy after two losses and just found out I’m likely no longer immune. I’m trying to find documents on the risk of miscarriage with measles in pregnancy but not finding much. Of course I hope this is a non issue but once again my anxiety with these cases is getting the best of me. TIA

Question - Research required Sleep Training a 5 Month Old

1 Upvotes

My LO has always had a tough time sleeping, during newborn stage it took at least 20 minutes of walking around bouncing to get him down for naps. Around 3 months that time went down and he started sleeping longer stretches, at night he would wake up once at that was it. At 4 months he quite literally started waking up every hour. We tried ferber method for about 2 weeks, and he started waking up 2-3 times per nice instead of every hour but would cry anywhere from 20 minutes to an hour and a half each night. We figured he wasn't ready for the training and started bouncing him to sleep each night. He has always cried inconsolably if he wakes up when you put him in his crib. He's 5 months now and I don't know what to do, my husband is now the only one who's gentle enough to get him down. I'm debating a sleep consultant or starting training again next week.. anybody have a similar experience and can offer advice? They say at 6 months it gets better.. not sure if I should wait it out.

We carefully keep him in his wake windows, watch for his sleep queues, have a nap and bedtime routine that ensures a dark room, white noise machine, etc.

Question - Research required How Damadging are Hot Showers and Baths to Male fertility

0 Upvotes

Me and my girl are getting to the point in our lives where we're starting to consider kids.

I haven't gotten checked yet, but one thing that I've recently been thinking about was how heat specifically when taking a bath or shower can affect fertility.

I'm a 28 year old male and have been cranking the heat knob to the absolute furthest it can go ever since I graduated Uni 5 years ago.

I take a hot bath first for anywhere between half an hour to a hour and a half and then take a 15 minute hot shower after that.

The last thing on my mind during that period in my life was having a baby. But not that me and my SO want one... I'm honestly terrified.

Any info is appreciated

Question - Research required Baby sleeping with parents

3 Upvotes

Our 10 month old baby has been sleeping in our bed with us for a while already. I know most people would put the baby to sleep in his own crib, but he would cry and not sleep if we did that. However, we really don't mind having him sleep with us since we have a big King sized bed. There isn't a risk of him falling since he is always sleeping between us or against the wall. Is there any negative aspects to doing this? Is there an age limit for having him sleep in our bed?

Question - Research required 14 hour trip (move) with 10 week old

3 Upvotes

Our family, which includes our 10.5 week old, will be moving soon. This includes a 14 hour car ride. We are thinking of breaking it up into 4 days which would include stops every 2 hours and the drive would be: Day 1: 2.5 hours Day 2: 4.5 hours Day 3: 4 hours Day 4: 4 hours

Does this seem safe if we stop for a feeding at the halfway point in each 4 hour day?

Question - Expert consensus required Antibiotics or not?

0 Upvotes

I know, I know, I’m not usually one to deny antibiotics. My son is 7 days shy of 6 months, has had a runny nose on and off for 3 weeks, a cough x1 and last night a fever of 101.1 I wouldn’t of noticed if I didn’t kiss his forehead. He’s been in a happy normal mood. Fever went away after 1 dose of Tylenol. Woke up this am rubbing one ear. Im at work so I sent my husband to pediatrician but I wish I was there to listen in. Amoxicillin (10 days) and triprolidine (7 days) was rxed. My baby seems normal and happy besides the fact that yes he’s napping a little more. Breastfeeding fine. The NP he saw today has given us conflicting information in past visits and is young and seems maybe just inexperienced. She did say one ear had an ear infection. My question is, should I give the antibiotics and harm the gut biome I’ve proudly cultured with breast milk if: my kid seems fine otherwise and had only 1 instance of ear rubbing, 1x fever, its unilateral? Im not sure if she said it was bad and I dont want my kid suffering, but he literally has seemed like his normal smiley happy talkative self.

Reporting Highlights

Unsanitary Conditions: Workers at one of the nation’s largest baby formula plants say the Abbott Laboratories facility is engaging in unsanitary practices.

Cardboard Funnel: In one case, workers said an employee used a piece of cardboard from a trash bin to funnel coconut oil, a formula ingredient, into a tank during production.

Federal Response: One worker complained to the FDA, but it’s unclear how the agency will respond. The Trump administration recently cut 3,500 jobs at the FDA in a mass layoff.

Question - Research required Thirdhand Smoke

0 Upvotes

First off I feel really worried because I’ve probably exposed my baby to thirdhand smoke because I’ve never heard of it before. My baby is now two weeks old and it’s only the past week that I’m worried about. My dad stayed at my house for a good bit of time the past week vaping in the house and using a weed pen. A few times he vaped while holding her but blowing away from her face. Obviously this is secondhand smoke so all vaping in the same room as the baby is gonna be stopped period. I too have smoked weed outside (nothing that makes me too impaired). I’m worried because neither one of us changed clothes or anything like that after smoking or vaping. I’m really worried about any harm this could have caused, she is growing fine and had great vitals at her appointment yesterday. Also I want to be safe in the future, is vaping in the house okay at all? Should I get an air purifier? Am I okay if I just keep a hoodie outside and wear it to smoke then wash my hands? I just really want to make sure no harm was done and I’m aware quitting is the safest option but I want to figure out a safe routine if family or I want to step outside and smoke.

Question - Research required Pavlik harness timeline evidence

0 Upvotes

My baby was put into a Pavlik harness at 10 days old with 2c hips. She responded to treatment after a week and we've been told to expect 12 weeks of the harness, with an hour out per day starting in 5 weeks. From what I've seen, it seems like length of full-time harness use (23-24hrs/day) is largely dependent on the doctor/institution. I have also seen studies which point to their being little evidence for 24hr treatment after hips are stable. I would love to be able to take her out for longer- I hate the harness so much, it has really impacted my mental health.

Can folks here tell me a) what your treatment protocol was b) how old old your baby was when you started and c) where you are located (city, institution)?

please do not respond telling me why the harness is important/why I need to follow my doctor's orders. I am looking to start a conversation with him based on what I'm reading and see what he says

Question - Expert consensus required Is the link between eggs and hormone related cancers significant enough to limit my toddler’s high egg intake?

A friend previously shared an article with me which made the link between eggs and breast cancer sound significant. However I cant find it, only this from 2015:

My question is, should I limit my egg- gobbling toddler's egg intake? Would choosing one type of egg (organic, duck etc) over abother make a difference?

Question - Research required Is it damaging for me to not see my child 3 days per week?

35 Upvotes

Thanks in advance for your help. I work a 3 consecutive day/week schedule with long hours and a long commute. My husband also works long hours with a varied schedule. My son is 14 months and the best boy! He is in daycare 5 days a week but during 2 days it's just half a day. We are just 5 weeks pregnant with our second baby.

It is not uncommon for me to not see my baby for a full 24 or 48 hours during my work stint. Even during the best weeks, it's typical for me to see my son to get him ready and drop him at daycare, and then best case scenario, feed him a bottle right before bed. It's typical for my husband to do bedtime with my son on days when I work because I rarely make it home by 7 PM.

As the mother, my son is quite attached to me. I love him so much. 2 days a week I spend with him 100% or the time. We play, go on walks and to the park, go to a music class, etc. 2 days per week he goes to daycare until noon (so I can get some housework done) and then I'm devoted to him all afternoon.

I'm finding it very difficult to balance work and family. We live in the US and make a good living, but I don't believe I could scale back on hours or become a stay at home mom (even temporarily) without having to move or change our lifestyle significantly, but I would sacrifice anything for this babe (future babes.)

I know there won't be any literature with my exact situation, but any evidence to suggest I am permanently damaging my child (or not) by being absent 3/7 days?

Thank you all for your time.

So my 11 week old had a high temperature last week 3 days in a row at night. Then on Saturday I seem to have come down with something which I'm realising now was strep (never had it before), im still struggling but not as bad.

Question - Expert consensus required Exposed to radiation while pregnant. It’s all I’ve been thinking about and I’m scared

163 Upvotes

I am 7 weeks pregnant and I haven’t told anyone at work. I work at mental health hospital as a Tech and yesterday a patient needed X-rays done. The nurse told me to go in there with him and the xray tech. Both me and the tech had on no shields or anything and I was standing behind her, it was in a small room and I was only about 4 feet away from her. She took 3 X-rays of his chest. After that, another nurse pulled me out and asked why I was in there and said I was being exposed to radiation and no young woman should be in there without protection. I didn’t know that. I thought it only affects you if you’re the one being scanned. So I immediately did some research and I started to cry. It’s been in my mind ever since. Is this really bad?

Hello all, searching for a new home, and we found the perfect one. However, there are power lines right behind the back yard. These are the steel H-frame type power lines. Not lattice structures. So I would characterize these as “medium.”

I don’t even know where to begin to look to determine whether this is a real health risk, or just an overblown fear. My child is 1.

Question - Research required How do I help my 15 month old understand custody exchanges?

90 Upvotes

We have had split custody since my son was 3 months old. We slowly worked up to 50/50 at 12 months. He’s now 15 months and I’m struggling with knowing I’m making the right decision by having him go to the door with me and tell him bye-bye and give hugs and kisses. He gets so so upset.

I just changed to this because the last couple weeks I would leave when he got distracted playing and the guilt of finding out that he gets upset when he notices I’ve disappeared is eating me alive.

What is the best/gentlest way to make these transitions easier? Every evening I stay for a while and nurse him, play with him and he’s so clingy because he knows I’m going to leave. Please help a sad momma figure out the best way to navigate this

Question - Research required My 13 month old baby was accidently given a double dose of Varicella vaccine at ONCE (was given ProQuad MMRV + another varicella vaccine) ...Autism and other health risk concerns.

0 Upvotes

I'm so stressed about this. Does anyone have any sound information or advice about if my baby will be alright with 2x the amount of varicella vaccine in him?

This morning, I took him in to have his 12-15 month vaccination of MMR and Varicella. It was supposed to be 2 separate shots But the nurse accidentally gave him a combined dose MMRV in one leg and Varicella in the other leg. which means he got a double dose of varicella. I've been freaking out and reading that varicella is linked to autism.

I already asked the doctor and they said he probably just has higher risk of the usual side effects such as fever, rash and possibly febrile seizure. I'd like to know if he has a higher chance of autism from this or other issues? What can I do about helping my poor baby at this point? Who should I contact to report this or what should I do about it? The dr had already reprimanded the administering nurse who violated the safety procedures. I'm in ventura County, California.

Question - Expert consensus required Sleep regression?

2 Upvotes

Help! I did EVERYTHING from consistent bedtime routine to sleep training but still my baby wakes up every 2 hrs average. She was a good sleeper from 3-4 mos sleeping almost 6-8 hrs every night, when she turned 5-6 mos she sleeps 3-4 hrs straight. I thought it was regression but it seems that she was sleeping like this until 8 mos when her sleeping got worse! :( I checked, she isn’t teething, no gas pain, no illness, no poop. I make sure to feed her enough during the day. All she wants is to breastfeed to go back to sleep even when my husband picks her up and dance her she couldn’t go back to sleep. We’re both already sleep deprived at this point and im starting to have this thoughts that im failing and im not doing enough. What am i doing wrong??? 😭

I totally understand both wanting to encourage solids and, if a baby is breastfed, wanting to slow that process down for the sake of the mom. But I keep seeing sources that push to replace formula with milk, and I don't really understand that. My kid obviously doesn't take a multivitamin, and isn't formula packed with all kinds of important vitamins and minerals?

So I knew I was supposed to offer the allergen to my baby at least once a week once introduced but I didn't know not offering the food once a week once an allergen is already introduced could CAUSE an allergy.
