hi Noni - i have had a bit of a routine for Noah since about 6 wks. at the start it was more for me but now i think he knows it is bed time as he feeds longer and does go to sleep quiet easily.
We shower, then quick massage, then feed, wrap and sleep. sometimes there is a nice cuddle and rocking in b/.n wrap and sleep - if he needs it or I just cant resist!!!
I used to start this at abotu 8.30 but now start at about 7.30ish - i dont have a strict time to start it depends what is going on and how tired he seems. I have also made sur i do the same thing no matter what time he goes to bed - ie even if 10pm as we have been out etc.
i think it gives them an idea of normality - maybe start jist doingthe same things (whatever works for you) for her???
