DD 7 months and is great at going to sleep herself but wakes often in the night. Last night she seemed to have a belly ache and I wander if she is having too much in the way of solids. She has porridge in the morning, half a jar and half yogurt lunch, half jar and fruit dinner. She sometimes also snacks on a rusk and cheese. She is not really interested in bf in day so should I cut back solids?
