Ouch ! I hope your youngest is okay !
At least you'll be able to thoroughly embarrass her when she's 16 in front of her first boyfriend (or girlfriend) by saying "Oh, don't worry about the way she is. We dropped her on her head when she was a baby." 😁
bahahah I mean, she dropped HERSELF on her head, to be clear. Just standing there and all of a sudden growing a goose-egg on her forehead lol. Kids, man.
