My 3yo LO tends to scratch herself before she sleeps. She seems to itch though I really do not know what she's allergic to. She does have mild ezcema when she was a baby. Do your kids do that too?

I use Derma e psorzema creme and it's really helpful. My daughter scratches herself till there are marks whenever her mild eczema flares. So I'll tell her the creme is poisonous (tho it's completely natural and safe) and if she touches it and puts her finger into her mouth she'll die.
