I don't know at what point we stop talking about this, but this year's height and weight:
Lily 45.8 inches tall and 41.5 lbs.
Madeleine 45.5 inches tall and 44.5 lbs.
So pretty much exactly the same height and weight gain since last year. Madeleine is on the 50th percentile exactly for everything - Lily is 50th for height and 25th for weight. We've pretty much had a consistent growth pattern since they were 2.
