I am a little behind on this since Ryan turned 6 months old on September 12, but he went to the pediatrician last week, and here are his stats: Weight: 15 lbs 9 oz Height: 25 1/2 inches Head circumference: 42 1/2 inches They didn't tell us the percentiles this time, so I'm not sure what they are. Ryan is such a joy. He wakes up smiling every morning. He can sit up now and loves playing on the floor with blocks or in his Exersaucer or Jumparoo. He is eating 3 meals a day of solids, in addition to formula. So far he loves all fruits and vegetables and rice cereal! We are working with him on rolling from back to tummy. I don't want to teach him to crawl just yet :) He doesn't sleep through the night yet but wakes up at least 3-4 times. Hopefully once his teeth come through he will sleep a little better!
