A.D.
My daughter did the same thing last month when she cut her first 2 teeth. She had never sucked her thumb before, so it surprised us. She only did it at dinnertime, and it was hard to get her to eat,too. I found 2 ways that worked to help get her fed. First, I distracted her with some of those puff finger foods that melt and slipped the food in while she was opening to down those. Then I tried chilling her food. That worked best. She actually kind of liked eating again and did not put up as big a battle. I also found out from the doctor that she was going through a slow-down in her growth and that she was probably just not as hungry as I was used to. (Her whole jar of food was dwindling to 1/2 a jar at times). Overall, I would say try the chilled baby food. Oh! and giving her a sippy cup of chilled water helped, too. She did just kind of play with it, but I think the cold felt good on her gums and helped her eat. Good luck! (PS_ She stopped it after the teeth came in, if that gives you any hope.)
