What not to do
Don’t force your child to eat. Pressuring will only backfire and make meals unpleasant for everyone. You’ll also be teaching him to ignore his internal signals for hunger and fullness, which can lead to overeating later on.
Don’t use dessert as a bribe. It may work in the short-term, but eventually your child will start hating the food you’re asking her to eat because she’ll view it as a punishment. Better to let her have a little dessert no matter what she eats at dinner. It’ll help her learn that sweets can be a small part of a healthy diet.
