I am posting this in both the breastfeeding forum and here since this may be the better place:
My DD is 12 weeks old and needs to be burped during our nursing sessions. If not, she usually spits up at the end. (Maybe I have a fast let down??) When we do co-sleep with her she will latch on and off and drift in and out of sleep, but often is awakened by gas or the need to spit up. I have tried to sit up with her periodically so she can burp, but then she doesn't seem to get back to sleep as easily. I have also tried rolling her onto her side to pat her back, but she rarely burps in that position.
