Hi, I Have A Daughter Who For The Past Few

Hi, I have a daughter who for the past few days has been scratching and digging at these bumps or bites... Some of them have healed better than others but I don't know why she is getting them. I have checked the house and our pet for bugs and have found nothing. My boyfriend and I have not gotten bitten by anything and I have checked bedding and washed everything of hers. Some of the bites/bumps also appear to have clear fluid in them. Other than that she is a happy healthy child.
