Girls, hello! Help! I can't figure out if it's diarrhea or not! After this pentaxim, the little girl has been pooping very watery, almost water. 2-3 times a day. There is no fever. It has lasted for a week. The doctor said that most likely it's some kind of non-infectious disorder, prescribed Simethicone and Aciphex, but there is no effect. I have already given him rice water, nothing. Maybe I am panicking, but before that stool was perfect. Maybe someone had a similar situation, how long did everything get back on track?
