Just returned from weighing Madoc. She is now close to 10 lbs, which puts her weight gain at 1.5 oz per day (they would be happy with 1 oz per day), so feeding is going well.
However, I'm still unable to put her down during the day, as she gets really unhappy - and she is still squirming around, holding her breath, turning bright red and then gasping for air. So I called the pediatrician, who thinks she may have a reflux problem. So we're going to start her on a little antacid and see if it doesn't get better - as she should be a happy bunny if her tummy is full.
