I'd agree just let her be her for a couple more weeks, honestly routines are wasted at too young an age they don't understand. I think Harry was about 4 weeks when we introduced the bath,bottle and bed and we had our 1st stn at 5 weeks (about 8hrs) He's had 3 naps a day since about that time too.
Our routine is:
He wakes about 8 or 9, has a bottle, a nap around 10.00 for half hour then a bottle, bottle and nap at 12.00 for about 3hours. Then a bottle at 4ish, nap about 5.00 for half hour and bottle at 6. Bath at 7.30 then bottle 7.45 and asleep for 8.00.
I recommend the book - sleep: the easy way to peaceful nights. We used it for Thomas too and i swear by it. Thomas dropped night feed at 10wks and Harry at 9 wks.
