Help! My 7 month ds appears to be teething. He went to bed as normal at 7pm but woke up again an hour later and was crying so much, I got him up again. Kept him up for a while (he was perfectly happy downstairs, although I didn't play with him in case he thought it was playtime) but once put back to bed he has been crying and crying. Have given calpol but this doesn't seem to have helped. What else could I / should I do??
