Hello, I can understand your concern. As you have rightly assumed, your daughter is going through the teething process. As new teeth are erupting in her mouth, she feels uncomfortable with the new feeling in her mouth. Because of this feeling, she is sticking out her tongue repeatedly. As she will get used to teeth in mouth, she will stop sticking out her tongue. She might experience excessive salivation and drooling, too. In addition, because of the irritation in her mouth and sore gums, she might be into habit of putting very odd thing that she can reach into her mouth. This causes stomach infection in many kids. Your daughter might have the stomach infection, too. Her excessive crying, screaming and sleeplessness can also be attributed to teething process as she herself is annoyed and irritated with the process. I would advise you to visit a pediatrician if she develops diarrhea and you can apply Orajel on the sore gums to make teething little easier for her. I hope this information helps you. Thank you for choosing HealthcareMagic. Take care. Best, Dr. Viraj Shah
