My little boy has always been a pretty dreadful sleeper. I Night-weaned him about three weeks ago, and now he wakes up three or more times a night crying, but settles back to sleep almost immediately when I put his dummy back in and give him a sip of water. Very rarely we get a 6 hour stretch of uninterrupted sleep, but I frequently find myself being woken every two hours. I'm back at work now and am absolutely shattered. How can I discourage this behaviour??? I usually put a couple of dummies in the cot with him at night so he can grab one and pop it back in, but either he doesn't find them or he has chucked them all out...
