Holy Crap I'm a Mom!

Sometimes it doesn't quite sink in that I'm a mother for the rest of my life. Then I realize that here it is, Saturday morning, and I was up at 4am feeding Riley, then again at 6:30am. Then for some reason, I wasn't tired, so I stayed up to clean the kitchen, do some laundry, etc. What happened to the days of me sleeping until 10am while Jeff took the dog for a ride to get coffee?
