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.

I have a huge supply of frozen breast milk already and so much milk in the fridge. During the day I produce about 6-7 oz of breast milk in a 2 hours period.I don't know if that's too much, but I know itâs more than what my 2 month old needs.
