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 don't allow my LO to scratch excessively given her sensitive skin. What we did was to use some creams eg Calendula to moisturise her dry skin once she starts scratching. It works in a way and she usually stops. :)
