My DS is 12 weeks old and loves to stand up, he can now support his whole weight on his own but I worry that although he's strong enough it'll be doing damage to his developing bones/ligaments etc. He was trying to stand up at his 6 week check and the GP didn't warn us against it.
I try to support him as much as he'll allow but he'll scream and shout if I try to sit or lie him down.
Could this be damaging him?
