My 14 month-old daughter has always had a small appetite. She has reflux, but it is controlled with Prevacid. When she started getting bumpy gums (only a few months ago) she went off most solids (except for a "mouse nibble" here and there). She cut her first tooth (right lateral incisor) at 13 months. The last two weeks, she's cut two more (bottom middle incisors) and has 3 or 4 that look like they will be cut in the next week or 2. The problem is that now she doesn't even want her bottle (forget about a sippy cup or straw at this point - she won't even put it to her lips). She's at the point now where she's averaging less than 20 oz of her Bright Beginnings Pediatric Soy Drink (basically a soy version of pediasure or boost kid essentials that the doctor recommended due to her small appetite and dairy problems). She's growing and developing normally other than that, but her weight is so low it's almost off the growth chart. I had just gotten it back up by switching to another bottle, and now it's going right back down because the second she started cutting those bottom two teeth, she wanted no parts of it. I've tried backing off on the pressure to eat/drink, but then she happily takes in nothing. Have any of you ever experienced this? Does anyone have any advice?

BTW: I've tried ibuprofen, Tylenol, and Baby Orajel. They seem to make her more comfortable, but have no effect on how much she will eat/drink.
