Kids appetites fluctuate. I find that offering them the food, but not getting too pushy is the best way to handle it. If she is teething, this phase should pass as soon as her mouth feels better. If you let her see you worrying too much over what she's eating now, you may help her develop some real "picky eater" habits later. I like to try to compare these things to my own reactions to food. When I'm not feeling well I don't want to eat much either, but once I feel better my appetite returns. Babies have the same reactions and we need to just wait those times out and watch to be sure that we are giving them the opportunity to eat but not pushing it on to them.
