Or when your 3 year old says, "Mom, I have pee-pee dribbles, I need to go to the potty" and goes all by himself.
Or when your 4 year old wants an extra hug and kiss (genuinely, not just to procrastinate going to bed) at bedtime.
Or when your baby sleeps for 3 hours at night. (It is rare, but boy is it delightful!)
Or when your husband takes the baby at 7am and lets you sleep for 2 more hours.
