The boys continue to lose weight and are now pretty much where we want them to be. Whitey weighed in at 13 lbs 0.5 oz, and Billy at 14 lbs 3 oz. We may want to up their food slightly now, but we'll wait a week or two to see if their current weights are stable.
Emily is getting positively chubby, for her, at 7 lbs 5 oz. She'll probably lose a little next week, though, as I'll be out of town and not available to feed her everytime she hops on my desk.
