Hi June,
I thought I would comment here than on the other site.
It really depends why you are wanting to get into a routine. Is it so you can plan your worktimes better, is it because she is getting grumpy when she doesn't sleep in the afternoon and it makes it all very hard for you? What is your motivation behind wanting more of a schedule.
I know a couple of other mums like Surfermum whose babies where really good at falling asleep and the parents didn't do things the same every day, so it wasn't really an issue.
The thing is, either some of our babies are a bit rubbish at falling asleep or getting enough sleep, when they don't have some sort of structure AND/OR our lives are quite structured and we really need a routine to ensure everything happens relatively smoothly for all the family.
If you do decide to try and set a routine, then the most basic one is to simply decide what time your baby will go to sleep and what time they will wake up. For most people this seems to allow either 11 hours sleep or 12 hours sleep continuously but some may be just 10. So depending on your household routines, think about what would be the best time to go to sleep and to get up. The next thing you may decide to do is to push for a big sleep in the middle of the day - this would allow you to get some work down, but clearly you don't want it to be in the afternoon when all the fun stuff is happening with your RL baby groups etc. It would need to be at a minimum 2.5 hours after she has woken up. And if she takes a big sleep not that long after waking up (it's hard to know how long she would sleep for at that time), then she may take a short nap later in the afternoon. Most people organise a lunchtime nap or a few I know an afternoon sleep and that will go on in toddler years to become the 'one' nap, so try and choose a time that will really work well for you both.
If you do decide to set down exact times though, your baby will come to expect things to happen at that time, so some people do build in a little flexibility if they aren't always sure they will be able to do everything exactly at the same time.
C'est tout. Bonne chance Juin.
