G has been an awesome eater from birth-in fact, it's the only thing in life he takes really seriously. We traveled for several days and came back Monday. All day Monday, he didn't eat well. He would nurse on one side for a few minutes (5 or so) and then pull off. Anytime I tried to get him to relatch he would cry and stiffen up. If I stopped trying to get him to latch, he seemed happy, would still sleep normally, etc. I figured it was just a crappy nursing day because we were traveling all day. The next day, we were back home and he had his 2-month appt and got shots.
The same thing has been happening with nursing all week. He nurses fine at night and will often nurse pretty well if I go into my room and nurse him side-lying in the dark, but he still fights nursing any other way after the initial latch and first few minutes of eating. He has always refused a bottle and continues to do so. He is having enough wet diapers that I'm not concerned about him being dehydrated, but I'm concerned that he's not eating nearly as much as he always has. I'd just nurse him laying down more, but with two two-year olds, I can't really disappear into my room for 45 minutes every 3 hours.

I called the lactation hotline at our hospital, and the consultant's response after a few questions was, "Wow! That baffles me."

Help! Any ideas what is going on? Suggestions on what to try?
