Hello. My baby is almost 4 weeks old, and we have had a new problem develop this past week. He is swallowing so much air while feeding that I am spending as much time burping him as I am feeding him. Usually about 4 minutes into a feeding he lets ago and I have to burp him and then he'll feed about 8-12 more minutes on that side and I'll have to burp him again before switching sides. Then he'll go about 4-5 minutes on the other side and let go because he needs to be burped. He'll go another 8-12 minutes on that side, and then he'll be done eating. At that point I usually have to spend a good bit of time getting all of the gas out of him. If I don't he'll spit up in his crib or wherever. Not only is this uncomfortable for him, but it is taking a large amount of my time. Every feeding/burping session is anywhere from 50-80 minutes. Any suggestions on how to keep him from swallowing so much air while feeding? Thanks in advance!
