My 6 month old has another tooth coming through and she's clearly been in lots of pain. It seems to bother her most around bedtime which means it's taken us an extra 1.5 - 2 hours to get her off to sleep, which is exhausting when most of that time she's crying. I've tried bonjela, doesn't work. I've tried giving her cold teethers but she doesn't seem to be keen on them. Any other things I can try?
