So after some quick googling i will definitely bring this up to the ped at my sons 12 month check up this month. Apparently, it can also cause speech delays and other problems. After reading more I really think this added to sore nips in the beginning because my ds's tie goes clear down, between his two front teeth and attach like on the front of his hard pallet instead of to his gums. So surprised that I have never heard of this before. Anyway, sorry OP, done hijacking now!
