ds naps and settles like a dream. It wasn't always the case but from 4 months he's been great. At 6 months he went for over a month sleeping 7-7 without waking. I thought I had it nailed. But in the past 2 months he wakes regularly 3-4 times a night. Sometimes he settles easily just by being tucked in and white noise on but other times he screams every time you put him down which goes on for half the night. Any ideas gratefully received.
