Girls, can you please tell me what it means if the baby scratches her forehead and temple when she wants to sleep after waking up and when she's nervous? Can she hurt herself while scratching her temples? She's been scratching her temples for a long time and is very nervous. I noticed that my hair has started growing well, so maybe that's why? There are no flakes, redness or rashes either.
