Re: Bad weight gain
I can't see how solids would help. If I wanted to gain weight I wouldn't eat a carrot, pea or peach - kwim?
That weight gain seems something to keep an eye on but no need to panic.
Maybe pump and top he up with a bottle? I found my girls would always take an oz or two out of a bottle after nursing even if they weren't really hungry. It's just easy for them.
