Baby not crossing the midline?

[Firstimemam]

Hello, I was wondering if anyone has experience this with their babies... my lo is almost 6 month, lies on his back and would never try to roll to the left or right ... yes some babies don't roll but they usually move their bodies to the left or right anyway! Same goes with his hands, his left or right hand would not move across his midline.... as if there is an actual line that stops him from doing it.

Has anyone ever seen/heard of it?

I'm no expert but 5m seems far too young to be worrying about this. Isn't it? I can't really remember but I find it difficult to imagine my two would have passed things hand to hand at that age. Talk to your HV if you are worried, they have a good perspective on what's normal and what's not.
