DS's sleep is getting past a joke, he goes down well most evenings and sleeps happily in his cot until about 2.30am then wakes every 40 mins to an hour. He will settle a little if he can sleep on either me or DH, but this isn't a long term solution as I am pregnant again and fast losing my lap and also I know that he likes his cot. He then wakes for the day at 5.00am and screams until he is entertained. His naps are good, an hour to an hour and a half morning and evening, although more often than not I have to be there. From the BW book, PU/PD seems to be a good solution but can anyone who has successfully done PU/PD please give me any tips, or even just words of encouragement. I am more than a little apprehensive! DH is "working from home" for the next couple of days so we are starting tonight.
