Sorry, I appreciate this should probably be in the food section but will just get a wider/quicker response here.
DS (19 mths) has always been a faboulus eater. He would literally eat everything in sight and fortunately that included fruit and veg as well as everything else. A typical day he would have cereal/and or taost for breakfast, and normally hot meals at lunch and tea followed by yougurt and fruit. On top of that he would have occassional snacks (mainly fruit and ricecakes but the odd baby biscuit/cakebar). On top of this he would beg (mouth open!) like a little puppy if anyone else ate food in front of him. It was actually embarrassing at times...!
Well two weeks on holiday (and probably more chips than he should have had 
have put paid to all that.
We have been back three days and he is refusing point blank to eat his dinners. I've tried making his favourites and encouraging him but I am lucky if he eats a few mouthfuls. The only things he will eat are a small amount of cereal in the morning, bread and cheese, yougurt and some fruit (although not other fruits he used to love).
I know I am probably making it worse by getting uptight about it and I realise that he is not going to fade away in a couple of days but it is making me a bit anxious as it is so out of character.
What I would really appreciate is any advise on how to get him to eat properly again. Should I just relax and ignore it and take the plate away or should I offer him something else (bread and cheese!) if he doesn't eat his dinner?
Also should I cut out snacks and if so, is that all snacks - including yougurts and fruit? It would just sem odd to deny him things that are good for him...
