Once again I am a week behind on posting these. I'll try to remedy that soon!
Andy had his four-month checkup on the 20th (though he was not actually four months old till the 27th). He was 24 inches long and weighed 12 pounds. Apparently we were going for the nice round numbers.
About a week ago Andy was on the bed with Doug, and he rolled onto his tummy three times in a row. It was downhill a bit, since Doug was making a dip in the mattress. He hasn't shown any inclination to roll onto his tummy when on a level surface (he doesn't like tummy time, anyway). He does go onto his side a lot.
