Pediasure milk is a food replacement drink, originally designed for children who are unable to eat real foods due to medical reasons. Marketing and greed has since aimed it at parents to convince them it is a good "top up" for vitamins etc, really you are just giving your daughter a milkshake (and not a healthy one at that) with a vitamin pill stirred in. If you are providing your LO a healthy balanced diet, why would you want to give it to her? And if you are unsure that she is getting a balanced diet then a multi vitamin is a much better option, this way she isn't filled up with fake milk and will have room to eat a better diet.
