My DS used to be a great eater. We did BLW so he had lots of different flavors and textures from weaning. Since he turned about 18 months old, however, he has just been less and less interested in food. I had about 3 regular dinners that I would make for him initially that he would always eat but now he's not even interested in them anymore! The only meal he will eat guaranteed is pasta and cheese with peas.
The only foods he regularly eats now are crackers and fruit pouches and yoghurt, basically things that require minimal chewing and effort. He used to eat all kinds of fruit and now he won't touch anything, not even his old favorite, bananas.
I asked his doctor already and she suggested that he is just bored in the high-chair and wants to be on the move so only wants to snack as he is very active. She suggested it was normal and just a phase. If so, when is it going to end?! He has to start eating normally again soon, surely...?
