Hi there. My son is just 5 wks old. I am breastfeeding him, with an occassional bottle of expressed breast milk. I am having some issues with nursing though. For the past two days we've been having a hard time. He latches on, sucks about 2 or 3 times, then pulls off and wails. This is how it goes the entire time. He also spits up a lot of it and has been having a lot of wet burps. I have been burping him and trying to feed him every 3-4 hours. He's been sleeping a lot the pas two days. I don't know what to do, I'm starting to dread nursing him because he gets so upset. Any advice would be appreciated.
