What vitamins can give you to a 15months old have weak lungs? he can easily have cough and colds.

Weak lungs?: I would not say your baby has "weak lungs". He is in fact being exposed to new germs every day and his body will be developing an immunity to them. It is a great idea to make sure that he eats well and sleeps well. Also, you can give him a good children's multivitamin and perhaps some echinacea as directed to boost his immunity.

Poly vi sol: Poly-vi-sol with iron is what I generally recommend, but your child's pediatrician may have another choice. Whether a vitamin is going to prevent colds is up for debate.

Multivitaminsforbaby: Give multivitamins to your baby once daily ,it has all the vitamins your baby needs.These vitamin s are available in liquid form .the dose is 1 ml once daily .Your baby should be seen by doctor at the earliest possible when he gets any cough ,cold so that it may not affect his lungs .
