My 10 month old has been a very good eater since we started feeding her solids at 6 months. She has been eating all sorts of things - she has 8 teeth, so has no trouble eating most table foods. She'd had nearly every vegetable and fruit that we've been eating for the last 2-3 months.
However, for the past couple of days she is refusing all food. Last night, she wouldn't eat anything but a few slices of watermelon for dinner. This morning, she refused her regular cereal. I still nurse her once a day (she was nursing full time until 6 months, and at least 4-5 months at 8 months, but now it's just 1-2 a day); however, my milk supply seems to be drying up. When she is hungry, all she seems to want is breastmilk, but it seems to cause frustration for her because she empties it very quickly and/or nothing comes out. She'll keep crying but continue to reject any other food that we offer her. Usually she loves eating applesauce, carrots, squash, rice, lentils, peas, yogurt - but now she isn't having any of that. She has always refused formula / anything from a bottle. We always give her fluids from a normal cup.
Despite her light or non-existent meals, she had four bowel movements (although darker than usual, but that could be blueberries) and enough wet diapers. However, she seems to be very lethargic/exhausted. She isn't her playful self and seems frustrated most of the day. She isn't sleeping as much either. What can we do?
Update: Never found out what was wrong with her; she ended up with a 102F a couple of days later. We gave her tylenol upon our doctor's office's recommendation. After that she woke up and ate a large meal. Now she is getting better again. Seemed like that she was just sick.
