A. Hello good evening !! Due to anxiety or deep thinking and in sleep sucking fingers are common. As the baby is doing in school might be anxiety issues check with the Developmental Paediatrician and try to engage in activities like scribbling,paper activity so that baby uses handa in the activity and avoid sucking fingers.
