DS is 8 months and we are still BF despite him biting every time he's teething. He has had 4 teeth one after another in the last 5 weeks and I am exhausted from being up all night as a dummy and from the biting. Every time he stops biting we have a few days and then we're off again. He has another tooth coming through (number 7, ffs) and I just can't face it again. He won't take a bottle(just bites and pulls them as he does if you give him a dummy) chews beakers, and will take a tiny bit out of a cup, but it is a messy business and takes about an hour to get an ounce in. What do I do?
