ok I know I have posted about this before...but I don't know why but I'm worried about my son not sitting up by himself yet...he's a big baby...and other children a few months older but smaller than him are sitting up and crawling...I just feel like maybe he should be sitting up by now...
@levismama1988, you're not alone my son is turning 6 months and he isn't crawling yet and he only sits up for a few seconds before he will fall back.
Don't worry. ALL babies are different. My two boys didn't set up till 6-7 month's && baby girl just started sitting up with less support and she'll be 11 month's in two days, but she's a preemie. So just give him time or talk to his pediatrician
my son didn't crawl until he was 8 months old and then he just army crawled and he is completely fine. all babies are different but if you are that concerned mention it to your dr and he will evaluate him that's what I did and everything was just fine :)
