that's easy - you don't! LOL. is there a reason why you would like her to be in a routine or do you just think that you *should* have a routine with her? A good place to start would be to sit down and write down everything that you do in your day and do it for one whole week. You would probably be surprised to see that you are already somewhat in a routine, only it is led by her and not you. There will be things you can see that she does around the same time everyday, maybe its a feed, or a big sleep or her bathtime etc. I have always found it so much easier to follow their lead and then I know that they are feeding and sleeping when they are hungry and tired and not when I think they should be.

Once you have your weekly 'timetable' you can sit down and work out where she is doing the same thing at roughly the same time and then perhaps implement things into time slots that you want her to do - like a bath or a sleep etc.
