Early growth spurt?

We went to the doctor yesterday, and was surprised to find that Jenna has only grown 1/2 inch and 1 1/2 pounds in 2 months! She's a normal sized 6-month old now, so I guess she was a BIG 4-month old! In any case, Jenna is right on track in development, healthy, and basically PERFECT! Here are her most recent stats:

26 inches - 14 lbs. 3 oz.
57th percentile for height - 14th percentile for weight!
