Small chest

So I have major insecurities about my boobs. I’m a 34a and I hate it. I hate not being able to wear cute shorts or cute swim suits. I see celebrities like Kate Hudson not have any breast area and it helps me love my small boobs, but then I get again sad all over again because my boobs are not normal size. I don’t feel like and adult and I’m a mom of 4!!!! I recently thought about breastfeeding again just go get my boobs back!!!!

I need advice on how to deal with my insecurity
