My DS has always slept through from 9 weeks...until the last month or so (he's just over 6 months old now) - I think it may be teething - he is not hungry (already weaned and not hugely hungry for breakfast) but wakes up grumbling quite a few nights a week - when I pick him up he is fine and smiley. Have resorted to giving him Calpol incase his teeth are bothering him, but worried we are getting into bad habits and he is just getting used to a 4am cuddle! Any advice?
