To all the mommy's out there.....

I need some advice. Brinlee really isn't on a schedule. I really can't complain because she sleeps great through the night and goes to sleep around the same time every night. But during the day it is always changing and I seem to never get anything done. (I know that I am a new mom and not supposed to have time to do everything that I used to, but I just mean like taking a shower) I am also afraid if I don't start one now that she never will be on one. I was just wondering what other peoples opinions were, what worked for them, and if they have any ideas on how I can start. Thanks for your help!
