Please call your pediatrician and, if necessary, get a referal to a pediatric GI. I have no idea how the bug bites might factor in, but my son had pretty bad stomach problems, even at your daughter's age. Strangely, constipation can cause runny poops because only the most liquidy stuff can get around whatever is plugging up the system. Also, you generally don't feel terribly hungry when constipated or having other stomach pain. Does her tummy feel hard and/or is it distended? Both are signs of tummy issues. The infant gas relief stuff is pretty worthless for real digestive issues, and there are lots of causes of stomach distress. Please, please take her to the doctor. There is no way anyone can diagnose what is going via the internet, and most of us are not doctors. Stomach issues can be challenging to treat, even for good general med docs (I have gone through them not only with my son but also with myself). For laypeople -- no way. Personally, I went through a couple of years in my mid-twenties where I would feel ravenously hungry, eat only a little bit, and then feel so bloated and full that I thought I might throw up. That was actually silent reflux, apparently, though I'm sure my having IBS contributed as well. I never had a fever; there wasn't an infection. It was incredibly uncomfortable and did not resolve on it's own. Meds helped as did acupuncture. In fact, when I first did acupuncture, I went to get help for my arm before going to grad school. The Chinese medicine doc refused to treat one area, saying that he treated the whole system one chakra at a time. I figured it couldn't hurt. The pins never hurt until this one he put in my lower leg. I let out a screach, and her looked at me quizzically and asked if I had stomach problems. I said yes, and he explained something about the meridian this point was on relating to digestion. Perhaps acupressure (pressing with fingers instead of inserting pins) would have a similar outcome. Anyway, I have not had the ravenous to full and nauseous in just a few bites thing happen since that time. I had not told the acupunturist about my stomach problems. Also, this happened 11 years ago. I once asked a friend who is a psychologist at UCSF if this could just be a placebo effect type thing, but she said that placebo effects don't last nearly this long (I stopped the acupuncture years ago). Just something to consider. No matter what, please get your daughter in her doctor as soon as possible. Please don't let people tell you she is looking for attention or playing you. She is too young for that. Sure, if she is getting lots of attention suddenly, she will continue a behavior, but she woukd not have come up with the idea to feign tummy problems, and kids eat when they are hungry. She wouldn't let herself feel horribly hungry for days just for attention.
