Young children tend to thrive on routine. Knowing what to expect and when it will happen makes children feel more secure.
For this reason, it is prudent to supply meals and snacks at exactly the same time each day. Because children need routine, you should avoid serving meals that are completely unfamiliar.
If you want your child to try something new, introduce the strange food alongside things you know he will eat. Let’s assume, for example, that you want your child to try carrots. If you know your child really likes chicken and mashed potatoes, you could try serving the carrots in conjunction with those two favorites.
