Thanks for the replies!
Several months ago my DH asked me if I burped our son after nursing. I said "no" and then wondered when the last time it was that I did burp him...two, maybe three months old? I guess I stopped trying when he seemed to do well enough on his own.
Then I thought, "I wonder how long I'm supposed to burp him?" Being a new mommy, I had no idea, and wondered what you all did.
I noticed there are a few Wendy's here too.
