I never leaked, and I breastfed both of my babies past a year with no problems. I never had a big problem with leaking even after my milk came in, so I consider myself lucky!
With my first two I leaked number three I didn't. Everyone is different good luck
i leaked colostrum before giving birth and leaked after my milk came in. you don't leak real milk until after the baby is born (if you are going to leak! i always had to wear breast pads) so i don't think there is anything to worry about.
