My 4.5 m/o doesn't like to sit. He will pull up to a sit when you hold his hands but seems very uncomfortable. He sort of flops forward. Whenever he's in a sitting position he will pop his legs up to a stand (of course, still holding on to someone and being wobbly). He is big for his age and has always had good neck control.
Does that seem normal? Should I just take that as a sign he's not really ready to sit even w/ assistance? My family thinks it's because he wears a big cloth diaper.
