DD is 7' DS is 3 and are both very fussy. They don't even like the same few things they eat. For instance, DD likes beans, DS doesn't. DD likes pasta, DS doesn't. There are so few things they will eat, preparing a meanl for both is a nightmare.
I have begun To simply give them food and if they don't eat it then take it away but refuse them pudding or other snacks later.
Any other suggestions on how tonget them to eat the same and vary their diets a bit more too.
