Hi my daughter who is 16 months old started with a cold and sickness about 3 weeks ago then 2 weeks ago developed a rash on her right leg along with mild diarrhea for 4 days, then after a week of the leg rash it went on her right forarm and now 4 days after its on the right side of her stomach! She cries out in the night and her poops still not 100 percent normal even though she's back to 1 poop a day, she's other wise fine in her self no temperature etc, what could it be?
