Q: If you wore a bra to bed, would it affect your breast's growing habits if you still developing? I'm 12 and I wear a sports bra. I have since I was 10. I was too scared to ask my mom for a new bra when the ones I had were getting tight, so I just stretched them and adjusted the straps so it fits. Eventually, I got a new one, but I heard it will help your development if you wear a sports bra or ANy bra while you sleep. Is it true?

A: I don't think it will help your development at your age. I think the rumor you're referring to is that women who are getting older can prevent their breasts from sagging if they wear a bra to sleep -- that rumor may or may not be true, but either way it doesn't apply.
Why are you too scared to ask your mom for new ones? It's perfectly normal and healthy for them to grow, and you can look forward to them continuing to grow in the next few years.
