Hello,
He's two and you won't be able to force him to eat and nor should you. However, there are things that you can try. I recently went to the Children's Hospital's Feeding clinic because my son was not growing properly. He has an underlying kidney disease. However, most of our time was spent with the dietician and the OT. The majority of the recommendations were very simple and are good ideas that I think any more could use sucessfully.
First thing, do not offer any liquids (milk, water or juice) before or during meals. They will fill up and then not eat.
All meals/snacks should be sitting down. Caregivers should sit at the table with child and eat. The only rule is that the caregiver MUST eat. Not the child. You should mimic smelling, tasting and eating your food. This was hard for us at breakfast as I am not a big fan of eating so early but you do what you have to do.
I'd also try a variety of foods but don't get to discouraged it seems that while my son was two (initially would eat anything, became very stuck in a rut and would not try anything.. this isn't as true nwo that he is three).
They also suggest playing food games -- like restaurant. Have your child help you cook. It is true that they are more likely to try something if they helped make it.
We also add instant breakfast to his milk for after meals. However, if calorie intake is not an issue I would not suggest this, You want you child to get as much nutrition and calories from his food as possible. Minimize juice -- it is a appetite supressant. Keep liquids to milk and water and after meals. Eventually, I did allow some water with meals.
Another, great resource is a book a I recently bought is called The Sneaky Chef and it has great ways to boost your kids favorite foods.
Good luck. Just remember this is probably the one thing your child is able to control --what goes into his mouth. Don't make it a big deal. All you can do is model and offer. He will eat if he's hungry (their calorie needs to reduce at 2). If you force the issue he will most likely just not do it and you are likely to create a food issue that may last a lifetime.
