Family member calling one daughter cuter then the other one.

Im a bit annoyed, well very annoyed my husbands side of the family are always comparing my two daughters. One is 1 year old and the other is 5 months old. They keep making comments on how the baby is gonna turn out cuter then her sister and i just give them a look like okayyy youve said that like 20 times already damn. I never want my daughters to feel as if they arent good enough in some ways. Has this happen to anyone?
