Late Nights with Baby

Why does it always seem like babies are born with night and day mixed up? My girl (3 weeks old) wakes up around 3am and goes to bed around 8am. My boys start getting up around 10am. Hubby and I like to go to bed around 2am. With a new baby I seriously don't know when I will ever get any sleep. I am so glad that my artist has been unschooling for a while now. I just need to figure out how to make this all work now that Hubby is going back to work. And I want to start writing on this blog a bit more than once in a blue moon. I want to be better at all of this but it is so hard being the mom. At least I'm good at late nights with the baby.
