Is anyone else’s LO not yet doing anything but sitting?

I try and encourage him to crawl and pull himself up/stand but he won’t have any of it. Especially standing, he has always hated me trying to get him to stand up and pull himself up and he never wants to put any weight on his legs.

I have mentioned this too the GP and health visitor and they don’t seem concerned but I’m just worried he is behind everyone else.

He is just happy to sit and play with his toys!
