Nutrition for 2 - 5 year olds

Dear Parent,
Commercially available health drinks may not be advisable because they are high in sugar. Children refusing to drink milk is one of the first problems every parent tends to face. However, milk should be a part of the child's diet to meet his/her nutritional needs, especially calcium. There are ways that can help your child to get used to drinking milk.
The best way to get your child drink milk is to add some healthy flavoring. Add a few dates to the milk for added taste.
Another option is to puree strawberries or other fruits into the milk.
You can also make your own health drink mix at home. You can use ragi, jowar, nuts and other millets to make the health mix. This mix can be cooked with milk.

Dear parent, this must be quite frustrating for you. My immediate response to your question is not to force your child to eat what he indicates a strong dislike for. Research has consistently shown that when coerced into eating certain foods, children develop life-long aversions to those food items. So if you really want your son to eat fish, don't force him! There are still other strategies you could try to get him to eat fish:
1. Does your son dislike the smell of fish? Many people cant stand the strong smell of fish and its completely natural. If that's the reason, it is possible that over time he may grow accustomed to the smell.
2. As you said you have tried different preparations and varieties of fish. Have you tried to involve your son in shopping for fish? Have him accompany you to the fish market and point out to different sea food varieties, whether the fish is fresh or salt water, which parts of the world that particular fish is mostly eaten, etc. The idea is to get him curious about fish and its use in cuisines the world over.
3. Have you involved him in cooking fish? When you're cooking fish, have him give you a helping hand in the kitchen. Show him different methods of cooking fish- from frying to baking to making a curry. Help him see how the fish changes in colour, texture, etc. when cooked.
But even as you try the above ways, ensure you dont force him to eat. Let him indicate whether he would like to eat it or not. Simply offer without the expectation that he will eat.
4. Fish provide an array of nutrients like omega-3 fatty acids, vitamin D and protein that are important for your child's development. So, get creative to get your child to eat fish. You can swap one ingredient for fish in the dishes your child already enjoys, such as sandwiches, pasta or a cutlet. Food that can be dipped into sauces seems to be more enticing for children. So, you can cut fish into chunks and grill them as lollipops or even make fish fingers.
