Re: "But I am not hungry"
nj, my eldest rarely finishes his meals. Middle son a bit more than half the time finishes. Little one, he's like me and loves to eat...he rarely leaves anything on his plate and asks for "more pleez" about half the time. Middle son is the one who was so attached to his milk - still is at almost 7. If I let him, he'd live on just milk and junk food. When he has a few meals that go pretty badly, I eliminate desserts and limit milk to 16 oz in a day and then he eats properly.
I do agree that its not a good idea to force eating. But by limiting their intake to the proper amounts of each food group, typically they'll fall in line pretty quickly unless theres some underlying condition. But something I've also learned is that when you say ok, they arent eating their meal so I'll make them something different or give them a big glass of milk...thats when you're perpetuating the problem. In the majority of cases, kids will eat when hungry even if it isnt something they particularly prefer.
