Cavities on a breastfed 14 mo

Yuyuita
Brooklyn, NY

Have anyone else have this problem, today we went to our first dentist appointment just to find out that she has cavities on her 4 front teeth, was really surprised since I don’t give her any juice, doesn’t drink from a bottle and I brush her teeth twice at day, I mean I try to do the best for her avoid any sweets stick to only fresh fruits and veggies, i can’t avoid but to feel terrible like how could this happened. The dentist recommended to wean her but I don’t think we are ready for that, I wanted to breastfeed her until she was ready... just feel like I’m failing as a mom
