so my boy is 10months old and can just about sit up unaided BUT he has to have someone behind him as he will fall over at any given moment...as for crawling...he dont all he does is roll about to get to where he wants!! abigail was sitting, crawling, standing by this age...and even took her first steps...now i know the "old theory" boys are lazier than girls but im at my wits end...i try and encourage him to sit crawl and even stand up but he just gets all excited and laughs 😕😕😕
