My son is 2 days old and is my second child. I nursed my daughter and didn't have too many problems with latching initially. My son keeps getting a shallow latch and my nipples are sore and blistered! I've tried getting him to open his mouth wider and then basically shove the nipple in as far as I can, but I don't know if my timing is bad or what, but it doesn't seem to be effective. Does he maybe just have a smaller mouth so is having a hard time getting a good latch? Could it be because he's still only getting colostrum and is too anxious to get his belly full of "regular" milk? Any advice would be so much appreciated!
