My 9 month old now has 6 teeth and thinks it's very funny to bite me when feeding which hurts alot! He has only been feeding first thing and last thing at night recently and he eats a good veriety of foods during the day and sleeps through. I stopped breastfeeding about 3 days ago but he won't drink formula, at the most he has 2oz a day if i give him it in a cup while he is eating can anyone help?
