My baby is 2 days old and I been breast feeding her only. My boobs recently got rock hard and very uncomfortable in pain they are. My baby doesn’t empty them all the time so what do I do? Is it bad to keep my breast so full ? And how do I get a better latch so I won’t be in pain and so engorging 😟😟
