If you like to wear Bras, you should wear a bra. If there is some reason that you don't think you should (such as if your mom says you're too young or you're a boy who knows it's socially unpopular), then balance other people's opinions with your feelings. It might be worth not wearing a bra for awhile, or it might be a better choice to wear the bra anyway.

yes you should
A baby should not wear a bra. It would be bad for their growth and support to wear a constricting piece of clothing.
This is a very personal choice. If you feel that you need the support, you should wear a real bra. If you are comfortable without a bra, or comfortable in a sports or training bra, you should stick with that so long as it is appropriate for your work or school.
