I posted before about spitting up and difficulty burping my 4-week-old daughter. The spitting up seems to be better, but she is becoming more difficult to burp. I can try and try with no luck. She seems to be very gassy--crying and arching her back--which makes it even harder to burp her. If she does burp, it is a big one, and she may spit up a bit with it. I'm not sure when to keep trying and when to give up. Sometimes I wonder if she is so irritable because she is gassy or because she is hungry and wants me to stop trying to burp her so she can eat more.
Any magic tricks/advice for burping a stubborn little one?
