From sleeping in till noon to waking up at 5:30am
Before kids I was that guy who valued sleep above almost everything. Would never get up before 9 or 10 on weekends. Now with the twins I'm up before they wake because that's my quiet time. Sounds terrible but I actually love my mornings now. Started drinking good coffee, doing pushups, reading. The sleep deprivation sucks but the routine and purpose is something I didn't know I needed.
Man, this hits different. I used to sleep until 10 on weekends and thought I was living the dream. Now I'm up at 5:30 with my oldest asking for cereal before the sun's even up. The weird part? I don't even miss it anymore.
