THANKS FOR YOUR QUERY.
Boost is a nutritional supplement that you can safely offer to your child, but there are better home made options available. Serve full fat milk and curd to your child. Do not skim cream out of milk. This extra fat is good for your growing child.
You could add a little ghee, butter or olive oil to your child’s dal or veggies.
Add cheese to pizzas, pastas and sandwiches.
You could also add cream to soups, jam sandwiches, mashed potatoes etc.
Make healthy desserts like kheer or carrot halwa with full fat cream.
Add nuts to your kid’s diet. Almonds and cashew nuts can be added to your child’s cereal. Raisins can be given for snacking. Peanut or coconut chutney can be given with idlis and dosas. However, nuts should be powdered or chopped fine as they can pose
choking risk. Read more on how to add nuts to your toddler's diet.
Add potatoes and other starchy vegetables in baby’s diet.
Add eggs and chicken to child’s diet if you are non-vegetarian.
Serve variety of food items to make meals enticing for your toddler. Do not keep serving same things every day.
Above all, make mealtimes pleasant and not a power struggle between you and your child. Do not force to finish everything on the plate. Ensure that your child is not getting all calories from junk food or juice.
HOPE THAT HELPS.
