Hi Bridy and welcome to you and Gabby. Sounds like you've gotten some good advice. The biting is normal due to Gabby's teething, and she will grow out of it. I know it is upsetting to your kids when she nips though--those baby teeth are sharp! Like Eleanor said, please don't hit her, but a light tap on the nose, accompanied by a sharp No, wouldn't hurt her. Also if you say No! and immediately fold your arms and turn your back to her, she'll begin to get the idea that nipping is not allowed. Give her plenty of acceptable stuff to chew on. The old coins in the can trick didn't work for me, although it has for some. Good luck, and please post some pictures when you have time.
