Girls, it seems like our teeth are hurting, everyone is gnawing with anger, crying, capricious, gums swollen, sleep has become worse, all of this can be endured. But the daughter stopped eating for three weeks, she ate poorly, only sleepy, and now she refuses altogether, she sucks normally three times a day, eats well at night... Tomorrow we'll go to the doctor. Maybe someone had such a thing? Can it be because of the teeth? And if possible, how long did you have such a period?
