Actually, knowing the difference that a day makes, Calvin won't really be a week old until 10pm tonight. We'll have to wait and see what other accomplishments he can squeeze into these last twelve hours. So far in his first week he: 
Lost 6 ounces, then gained five back; Lifts his head during tummy time, and while on his back; Has rolled back onto his back during tummy time twice now (we know it's just luck, but we'll count it anyway); Has aquired the ability to sleep peacefully for a five hour stretch, which the doctor said was fine now that he regained his birthweight; Went for a walk; Has tried out all his toys; Has received visitors; Has learned to take his bath in stride; And has basically defeated the jaundice just by being a pro at nursing. We think it was a successful week.
So those are Calvin's accomplishments...what about ours? So far, in our first week as parents, we: Have learned how to get a decent night of sleep; Have become pros with diapering (we've caught all baby boy showers in a washcloth!); Have learned how to calm him when fussy and burp him after feedings; Have survived two baths, two car trips, and two doctor's appointments; And have gotten better at putting him down every once in a while, at not looking at him every few seconds while he's sleeping, and at sharing him when we are both home and awake. This, too, feels successful to us!
