My Daughter is 22 months and just got over the flu but?

I have two little ones too. and yes its normal, she is probably still not feeling completely herself. give her a couple more days, and let her eat what she wants, within reason. such as if she is willing to eat noodles of crackers, let her, something is better than nothing, and pedilite will help too, it has calories that will help her feel better too. i hope this helps.
