Question - Expert consensus required Looking for more detailed info on developmental milestones

By more detailed, I mean like more statics related to when babies and toddlers meet different milestones. Like ranges, means, percentiles, etc. Most of the milestone information I can find is geared towards identifying if there is a delay. I’m more interested in like X percent of babies have 100 words by 15m, 18m, 2y, etc.

My toddler has been meeting milestones early, and my husband is convinced he’s a genius, but I’m pretty sure he’s just a little ahead average. lol But it’s made me curious like where he actually falls compared to most babies in different areas of development, mostly for curiosity sake.

I know this info has to exist bc it’s what they use to make the CDC milestone charts, but I’m having trouble finding it.

The Denver Development Screening Test might be helpful for you. Here is a PDF link.

Interesting, kind of hard to use on a phone.

BTW, does meeting milestones early have anything to do with better skills? Like a child that rolls over at 2 months will be more athletic than a child that rolls at 7 months?
