There are several things that I do differently now that I'm a parent. I'll smile to myself and think, "I know I'm a Mom now!".
You know you're a parent when....
You baby is sleeping and you run out of the room to sneeze, open a bag of chips, or anything else that makes the slightest sound. When your baby is sleeping EVERY sound is loud.
You'll sit in the same position without food, water, or bathroom breaks, as long as your baby is sleeping in your lap.
When your baby starts to nap in the other room and you watch the monitor instead of the TV.
You can do almost anything with one hand.
You can accomplish anything in 5 minutes or less. Eat a full meal, shower, do a load of laundry.
If you know what I'm talking about add to the list. Or just laugh along with me :)
