When I went in for my daughter's six month check-up, the pediatrician told me to start supplementing her diet with a multi–vitamin as I was still nursing. Surprised by this, I sought my mother's advice.
She's a pediatric nurse (lucky me!) and said it was normal having given the supplements to us when we were little and to follow the doctor's advice.
After doing some research, I decided that the doctor and my mom knew best.
According to the American Academy of Pediatrics:
"Liquid multivitamin drops with vitamin D are available. If you give your baby the recommended amount from the dropper in the vitamin drops bottle, the baby will get all the vitamin D needed to prevent rickets."
Some people believe that by taking your baby for a walk in the sun every day, that the tot will absorb the Vitamin D they need. The AAP says that sunscreen, which we have long been encouraged to use, can keep baby's skin from producing Vitamin D in their clinical report.
I know some parents don't believe in supplementing their baby's diet and I respect that point of view. But, I also believe it's better to make informed decisions than to not know your options.
