I've been pretty lucky so far in that all my dck's eat my food. Some don't like certain parts of the meal and fill up on other things (ie. one won't eat fish, but will eat the vegetable and grain). I serve what I serve and they eat what they want. I don't stress over it one bit. I don't even "encourage" or coax in any way...I put it in front of them and they choose whether to pick it up and try it or not. However, that said, I have started them all as babies with me, so it is much easier to get them used to my food. I think it may be more difficult to start a 3 year old who is used to eating junk food as I don't serve any! My own 3 year old is picky...I serve him what we are having and he eats or doesn't eat. One thing I do with him is that if he doesn't eat at dinner time, I will put his plate in the fridge for when he inevitably will ask for something else a couple of hours later
