Congrats. Brother just became a dad last Saturday and she was a bit smaller at 4lbs and 14oz and is doing fine. Size doesn't mean as much these days. Something tells me that smile ain't coming off your face till she brings home the first boyfriend.
Congrats to you both. Our daughter was 5 lb 11 oz when born but only 17.5" long. She finally hit 8 pounds this week at just over 2 months old! They are awesome. The greatest thing is when they are sleeping on your chest. Maddie and I will take naps all the time in the recliner.
