My 7 month old has two bottom teeth and ever since they surfaced it's been a nightmare, they have given her a large ulcer under her tongue which reduced her feeding and she started losing weight, at only 9lbs 6oz she can't afford this and is now on high calorie milk and gaining weight. This started before Christmas and she still has the ulcer under her tongue and now pretty much the whole of her lower lip is ulcer, they often bleed and feeding is painful, she has started sucking on her lower lip which makes her writhe in agony but she still keeps doing it. We have tried teething bonjela, calpol, Nystan for thrush, Calcium Carbonate from the homeopath, Diflam spray to numb the pain for feeding-although have stopped using this as when numb she can bite more freely. I am absolutely desperate now, help!
