My DD is 15 months old and she has recently started cutting her back teeth. Her gums are always very swollen and when she was laughing the other day (which has been a rare occasion lately!) I noticed that all 4 of her molars are coming through at the same time. One has cut through completely and the other 3 have bits of teeth cutting through.
Was just wondering if this is normal for back teeth, her front teeth came through one by one. This would explain why she has become very miserable lately!
