He's always slept so well and drifted off by himself multiple times during the day. This week, almost overnight he refuses to sleep at all and he's getting himself so worked up. We've tried ignoring him, giving him a dummy, rocking him to sleep, feeding him, baths, lullabies, massage, babywearing for long walks - at most he will drift off for half-hour- one hour but will wake himself up and start grimacing. Most of the time he just grimaces until it builds up to a full-blown cry. I don't think he's colic because he's had that before and that was different he was straining but he never cried. He's always been such a chilled baby - we are pulling our hair out right now :(
