my doc told me to put my 3 week old on Alimentum formula and pedialyte due to constipation which I hope WIC covers this formula. I just don't understand why I need to give her pedialyte if she's not vomiting or dehydrated. he said to.give her 2 OZ but not all at once. this is so confusing I have no idea how I'm only going to.give her a little at once.. anyone have advice?
