You and your sister both need some serious health education.

They do grow during pregnancy. That aside, 34A sounds very cute. Is she single? Lmao.

Yes.. My son's mother went from a 32C to a 32DD/E..

Breast size has nothing to do with supply.

Yes with your breast milk

yes they get bigger and they will always produce enough for baby unless they become engorged and yes i have studied this i am a med student

I was also a 34A, had no problem producing plenty of milk. She should stop worrying.

Nature takes care of that

yes
