My dd is 15mth old and just will not eat her meals during the day. She eats brekkie no problem and will eat snacks (fruit, cereal bar etc) but hardly anything at meal times. I've tried BLW, different foods; pasta, fish, veg all of which she's eaten before. She goes to nursery 3 days per week and eats everything! When she doesn't eat I get stressed. Is it true that they'll eat when hungry?
