Good morning S.,
I empathize with all of the teething symptoms and not eating is definitely one of the top 3! During all of the teething bouts my 18 month old daughter has gone through so far, I always made sure she had lots of liquids, of any kind as far as various juices diluted with half water and plenty of popsicles, italian ice, things like that to make sure she got her fluids so she didn't get constipated in addition to her teething. Once the teething is over, she will make up for lost meals!
