Basically he started weaning at 6 months and initially ate a variety of food. Since a horrible cold a week ago he has refused everything except yoghurt mixed with fruit (plain yeo valley full-fat yoghurt with fruit puree) He cries and refuses to eat anything else. Would it be the worst thing in the world to just go along with this for a few days and hope he comes out the other end soonish? Surely this isn't that bad for him?
