Apparently it's been proven breast feeding does not cause the breasts to say, it naturally happens with age and or if you lose a lot of weight in a relatively short time, like I did. RIP boobs!
Its not the breast feeding that makes them sag, its being pregnant that does. Just them increasing in size during pregnancy then going back down after will cause that little sag that almost every mom has. If its your first tho you might not notice it that bad, im on my third and my so called breast are going to looklike a couple of wind socks on a calm day.
As long as your wear a supportive bra you won't get saggy breasts. I breastfed my three kids and am going to breastfeed this one to and my breasts are pretty much exactly the way they were before my first kid (slightly bigger because of pregnancy but otherwise the same). Its important to wear a bra almost all the time, but if you breastfeed you may want to anyways because of leakage.
you will def lose weight fast breastfeeding. It burns like 500 calories when you do it. As far as the sagging goes, a good supportive bra is key, you could sag either way, but if you have a good bra, it will help them stay up
I didn't and mine kind of sag cuz i didn't have a good supportive bra when they were full of milk and so heavy. But i heard breast feeding make your stomach go down really fast
