He can hold his head up- it bobs around but he does hold it up well. No signs of rolling at all but I know you have to wait for 6 months I think? I just thought at 4 months there would be signs of rolling but no signs at all and thumb always across palm
are there any other symptoms that would indicate cp? any risk factors? i personally wouldn't be freaking out yet if that's the only thing you've noticed but maybe give your pediatrician a call?
