My son is 5 1/2 weeks old and last night I believe that he was tired and not hungry, but wanted to nurse to be close to me. I cuddled him up for a while, but the only thing that he wanted was to nurse. Of course I nursed him, and when I went to pick him up to put him in the swing, he spit up what seemed like all the milk he just got! He's done this several times and each time I get frustrated, and he never cries or seems bothered. I've read about comfort sucking/non nutritive sucking and am wondering, do babies learn to comfort suck on your breast without getting so much milk? I love having my baby close to me but don't want to have to change his (or my) soaking wet clothes each time!
