It doesnt make ur boobs sag.. It actually gives u a fuller figure... But cons are prolly:
definetly nipple soreness in the first week.. Afterwards it dont hurt but still does then..
U cant really go out due to breastfeeding.... So u hafta be with ur child all the time...
I didnt find the diapers smellier, I actually found it smellier on formula (i guess it depends on what the person eats tho!)
u cant eat choclate or certain things becuz some things baby might not like and could be up all night..
I love breatsfeeding tho and will always do it with my babies! Lol!
