Help! Teething?!?

Kendra • Just had my twin girls on June 10th
I think my girls are starting to teeth! Chewing on hands and fingers all day long or anything else they can get their mouths on, flushed cheeks, crying all day, interpreted sleep, red bumpy gums. Any advice ladies? When did your twins hit this stage? What did you do? And please tell me how I can survive lol
