Your moisturiser would be fine... maybe you should declare it as food when you enter the states but they wouldn't take it off you. I wouldn't even bother declaring it as it's a cosmetic.

Wear shoes you and your daughter can slip on & off easily. Children are not to go through body scanners (they shouldn't suggest it but good to know your daughters rights) and if they suggest it to you I'd ask for the pat down instead personally.
