We took Claire in for her 4-month checkup with the pediatrician today. She weighs 11 lbs 15 oz (10th percentile) and is 24 inches long (25th percentile). He listened to her lungs and heard good breath sounds all around. She breathes a little faster than the average baby, but he said that's normal for her. He wasn't concerned that she isn't able to lift her head up yet when lying on her tummy. He was very pleased that she hasn't been sick so far and said we need to try to keep it that way this winter. She got lots of shots today, but I gave her Tylenol before we went and she didn't cry as hard this time, so I was relieved.
