I tend to agree about feeding, also. It is a source of great anxiety for many parents, though, so I do empathise with those who try to encourage more eating! My husband has only recently let go of the idea that our kids need to eat lots to sleep - there really has never been any correlation between the two things for either of them!
I remember trying to force my son to feed when he was a little baby and I thought he needed more - we ended up with breast refusal! It does often backfire.
