It takes about three days to four days for your milk to come in, if youâre a first-time mum. If you've had a baby before, it can happen earlier than this. Your breasts will start to feel full a couple of days after giving birth, which is a sign that your milk is coming in.
Yes, it's completely normal, and is nothing to worry about. What's leaking is the first thick, creamy milk (colostrum) your breasts make before producing breastmilk. From early pregnancy (about 16 weeks), your breasts will have been preparing for the birth of your baby by making this high-protein substance. Some women leak quite a lot of colostrum, while others don't leak at all. Leaking won't make any difference to how much milk you produce once your baby is born. Leaking can be a nuisance, but wearing breast pads inside your bra will absorb the fluid and prevent wet patches from appearing on your clothes.
