No comparing babies! I have kids all over the spectrum - DD2 is in the 3rd percentile (22 lbs at 2.5), DD1 is in the 60th (38 at 4.5) and Becky is in the 98th (nearly 15lbs at 2 months). They are all healthy, happy, and growing at their own rate. Don't over think it. If you start comparing now, you'll spend the next year worried, because there are going to be a lot of milestones, and they'll all reach them at different times.
