For the past two weeks, my 12 month old has been waking for between one and two hours at least once a night. He's never been a great sleeper (he's slept through the night about five times total) but it's always been pretty easy to resettle him until recently. He's getting his molars at the moment. Please tell me this will miraculously resolve itself once they've come through and I can get a half decent night's sleep again. Please.
