Small head baby

I think I’m just looking for a little reassurance. Her doctor isn’t concerned, but he’s also my doctor and I know he tends to brush things off.

My baby had her 4 month appointment today. Her height and weight are around the 95th percentile. Head is about the 10th. Her doctor said it’s following the curve. I can’t help but worry a bit though.

She’s doing great with hitting milestones, mostly on the early side. So I know it’s probably fine.

Anyone have such a big difference with head size and body size?
