I think despite being quite a laissez faire person, and cosleeping, breastfeeding etc, our days are quite defined really what with school, creche etc. While the first 3/4m with a new baby I think it just tags along, feeding whenever it's awake, but then I think a certain amount of pattern to the day, if you have other children (I have a big one as well as twins) is useful for everyone's sanity... for eg my twins used to either sleep when they arrived at the minders, or if they were with me they would sleep in the car and the buggy on our way out somewhere, so i could book classes etc or go places knowing they would be awake and in a good mood by 10.30. When you have twins, getting them to nap at the same time is the hole grail, obviously. They then used to nap after lunch, unfortunately they really would have liked to sleep 2-4 but that didn't suit either me or the minder doing the schoolrun! But we managed... they were still often doing 2, but sometimes one nap, at 16m when they started to go to creche 10-12 4 days p/w and that has fixed them in a very solid routine, napping 12-2... though they will still nap at 10am and 3pm if we go out for the day in the car. I think, in short, trying to keep to a comfortable pattern each day with the older one, the little one will fall in, and even though sleep needs change as they grow, the times of naps will suit you and you can be flexible as eneded, whatever suits you.
