Our 20 week old DS we think is teething (little white bumps on lower gums, dribbling, hands in mouth, flushed cheeks from time to time). Sleep was (!) ok, went to bed half 7, slept til at least 3, sometime even longer (bliss) but last couple of nights has stirred just an hour or two after bedtime and yelped/whimpered. Then woken up regularly, only soothed by cuddles or a dummy. Tried Calpol last night but can't do this every time he has a bad night. What can we do (DH really suffering from lack of sleep!) and how long does this last? (new to mumsnet by the way)
