I had my son last Wednesday and everything was going great w/ breastfeeding him. His latch was pretty good and my nipple soreness had finally stopped. Well all of the sudden he doesn't want to latch on. He will for about two seconds and then pulls off and does this over and over again. I'm at my wits end and I don't know what to do anymore. He tried nursing on both breasts for two hours this morning and never latched on well. I finally had to pump and give him breastmilk in a bottle (which we have never done so its not nipple confusion). Any ideas?
