I hate burping PK. Not because of the spit-ups that sometimes accompany her burps, but rather because it is so freaking difficult to get her to burp!!!
When she was first born, I tried burping her by sitting her on my lap and supporting her neck with one hand while patting her back with the other. Not only did she look like a sad little frog, this position made her squirmy, did not usually produce a burp, and more often than not made her barf out her food because I sometimes got the angle she used to sit on m lap wrong and it put pressure on her teeny diaphragm.
I soon gave up o the sitting down burp and moved to the over-the-shoulder burp. While I burp her I usually move my hand up her back as I pat it. This type of burp was definitely easier than the sitting down burping method and is my method of choice, namely because it produces some good (although sometimes infrequent) burps. Even though this is my method of choice, however, I can't seem to get her to burp as often as I'd like, which of course can be really frustrating because oftentimes she'll refuse to burp but actually should burp because the gas makes her cranky. I worry about putting her down for a nap after a burpless feeding. Who knows if she can end up gagging or something from spit-up as a result of not burping!
Today I tried a slight variation on the over-the-shoulder burp, courtesy of my sister-in-law. Basically, while PK is slung over my shoulder, I slowly yet firmly smack her mid-back while burping. This definitely seems to work better, so I think I'll stick with that.
