Discrepancy

Gunner was weighed and measured again on Friday, two days after his doctor's appointment. On the same scale, with the same measuring system. Here's what we got:

Height--29 inches

Weight--24 pounds (which puts him in the 75th percentile, instead of 60th)

I almost had the lady do it again, just to see if we could get a different third set of results, but I didn't. I guess it doesn't really matter. He's still as healthy, sweet and cute as can be. But I am curious about why there was such a discrepancy.
