Burps and Spitups

She's doing a lot less of them lately. In the beginning I had to burp her every single feed-- once in the middle and once at the end at least. She used to spit up a few mouthfuls a day as well. Now she'll spit up only once in a while and today was the first time I thought she needed a burp-- and she did-- in a couple of weeks at least. Just before that, I was touting her as a champion burper. She could really let 'em rip.
I don't remember her big brother needing any encouragement to burp. He'd just produce them once in a while unexpectedly. She'd a tad colicky, I guess.
