5:00 am. Every day. It's lots of fun.
Seriously, my daughter is up between 6-7 most days so if I don't get up at 5:00 I wouldn't have any time to myself at all. After I get out of work I pick her up at my moms, come home, make dinner, play with her, put her to bed, do dishes, pick up the mass destruction she left behind, and then I'm too tired to do anything else. It's honestly the only time for me to do it.
