I'm with Kelly I started rituals (that's a good word ) from day dot with both of mine.
With my first she fell into a good pattern right from the start.
With DS it took a bit longer, he was probably around 3 or 4 months before he started "knowing" what was coming next and he then became alot more predictable.
Now it's great because the two of them have a great pattern going now and they both know what's coming next and things are so much easier.
Basically I just did the same things in the same order most of the time - I was never a clockwatcher or strict about it but I did keep things predictable and it helped us alot.
