just had my daughter at 4:10 am yesterday and she hooked on one breast and won't take to the other one but that one is really sore



Congratulations! maybe you have less coming out of that side, maybe try and put a few drops of colostrum on that side to get her to latch. it can take about 4 days for your actual milk to come in. could also be the way you are holding her, maybe try a different position.
my boobs are like that. I feed on the left (strong side) 3 or 4 times then I give it rest and use the other side.
