Hello girls! I have such a question, our teeth are coming out, and the little boy is worried at night, sometimes he cries so much, during the day many times it hurts, green poop, what can be done, how to help? So that he could rest even at night. After all, he wakes up once or twice at night and cries. P.S. The pediatrician says everything's fine, the teeth are coming out.
