DD is 6 months and her first front (bottom) tooth started coming through a week ago. Her second tooth has now started to come throught too. She's has several disturbed nights but last night was terrible; she was waking every 10 minutes or so screaming; Calpol bought her a couple of hours of relief but I don't want to give her too much. Both teeth are now visible - is the pain likely to last much longer for her? Thanks in advance
