Routine in young babies isn't a necessity, but it does help some of them settle easier.
I have my 10 1/2 month old son in a routine, as he has an older brother and sister who both go to school, so his routine is worked around getting them to and from school. I find now, that he will settle much easier as his body knows when it is time for sleep, when it is lunch, dinner etc.
The disadvantage I have, is when we are out, or on a weekend when things are different, he can get a bit grumpy. He is the type of baby who only likes to go to sleep in his own bed, and doesn't settle very easily if we out...unless we are in the car.
In your circumstances, I wouldn't make a big deal out of a routine, until she gets a little older and closer to school or kindy age.
