I agree with just about everyone that posted.....call for help. In the mean time... tell her to put a little bit of milk on her nipple before she tries to get the baby latched on. My husband and I almost got a divorce the first night home, cause all he would scream is "give him a bottle, he wont stop crying!" and I screamed "I will not give him a bottle, never!" Its a stressful time, tell her to relax and everyone around her too! Relax, try the milk on the nipple, it gives the baby a taste and it then they try to suck to get more. It worked for us! No worries, were still married and my son has been breast feeding now for 7 months. Good luck and call for help, there is so much out there!
