Baby biting fingers

Katie • ...

My son is one and is just cutting his second tooth. He has one on top and one just cut on the bottom. My issue is he always bits his fingers and they are all cut and red (dr appointment booked) I don't know how to get him to stop biting his fingers! I offer him teething rings, I've tried a few different types to see if that helps but he just ignored them and bites his fingers! They are starting to look really sore and I'm reluctant to put anything on them as it'll go straight in his mouth!

Any advice on how to get him to stop?!
