We have to burp here. I don't remember burping my other two so much. Jonah always has air bubbles! He will fuss a little and acts like he is hungry. He normally burps after just a few pats, and he is perfectly relaxed after that. He spits up very little, I think mainly it's because he gets overfilled. My first DS spit up all the time! It is so nice to have a baby that doesn't do that.
