Sammy hates bows. She will scratch or roll on her back to get her topknot out at least once a day. I just have to keep re-doing them. Usually I put it in, she takes it out and I put it back, and then she gives up and goes to take a nap
Do you take them out at night? Sometimes that helps. They are scratching because it is uncomfortable. Try putting it in looser or using a looser band. Also, I use claw clips on Sam and that helps the band stay in and looks cute without having a bow in her hair.
