If you have medical advice supporting your wish to provide your child with a multi-vitamin, knowing which one to select can be helpful. It is very important, however, to explore thoroughly dietary changes before turning to vitamin supplements as children should really get all they need from their diet unless they’re very picky. Be sure to have your child’s doctor’s advice at all times!
Consider whether there might be any essential nutrients your child is missing. Is your child milk-intolerant and perhaps needing more calcium? This could simply be a case of feeding non-dairy calcium sources or looking for a quality supplement. If your child is a vegan, there may be a need for supplemented B-12. Or, you may just want your child to take vitamins so they grow up healthier. In each case, don’t guess; get proper medical advice first to ascertain the specific needs.
Find the right form of vitamins. If your child has problems swallowing vitamins, avoid purchasing ones that have to be swallowed. There are vitamins that can be chewed, swallowed, or even mixed into the child’s food or drinks.
Use the right amount only and nothing in excess. Read the instructions on the product and heed your child’s doctor’s advice. There is such a thing as overdosing on a number of vitamins. Moreover, many vitamins come with additives such as lactose, sugar, starches, etc. that might cause other problems in your child’s diet or digestive system.
Always seek advice before medicating a child. Unless you’re a trained pediatrician or nutritionist, it’s not likely that you’ll be aware of all the issues involved in providing supplements to your child.
