I'm 25 weeks pregnant n still wearing the same bra size. only a little enlargement. i've read that it should increase a cup or two. can i breastfeed?

Yes of course: A lot of women confuse the size of the breast with the amount of breast milk. There's, to my knowledge, little correlation, as a smaller breast can fill with a lot of milk and empty out easily. I wouldn't worry for a second. I will be honest, however, i found breastfeeding to be challenging. Brought me to tears. Just be thankful what what you do have and know baby will be great.
