We did (and still do) have a routine driven child but she seemed to have a pattern pretty much from the start. It was encouraged as she was slightly jaundiced and quite small so we had to wake to feed every 3-4 hours to flush out the jaundice. Anyway she was in a definite 4 hour cycle early on, however I found that she tended to sleep better with some motion. So I always made sure at least one of her day sleeps was in the pram and we would go out for a 2 hour walk every day - rain, hail or shine. This has added benefits as she will still sleep in her pram anywhere which is a godsend!! Plus the exercise did me good as well.

I was given Tizzie Hall's Save Our Sleep book and found it to be very prescriptive and not really suited to our lifestyle however it was really useful in providing information on how much sleep DD should be getting at whatever age she was at.
