My just turned 5 month DS is on the 75th percentile for weight and height - this may be relevant. I'm worried about his physical development. He is nowhere close to rolling. He still hates tummy time and lasts 5 minutes at most before face planting and crying. He still has a bit of head lag when pulling to sit. He lifts his head a bit doing tummy time.
On the plus side he is quite sturdy when you hold him on your knee and doesn't need loads of support, this is how he prefers to be. He is also reaching for toys in his toy arch.
Socially he seems ok, he is very chatty to us and his teddies, loads of smiles. Worships his older brother and is constantly trying to catch his attention with squeals or big grins.
But he seems behind in his gross motor skills? Should I be worried here?
