Since Ethan was about 5 months old, when Abigail was 26 months, these two kids have been about the same size when it comes to weight. Always within a pound or two of each other we have watched them grow and grow together.
But it sure did make me laugh when we went in for flu shots the other day and the scale for both of them was exactly 31 lbs 6 oz. 21 months apart in age and 3 1/4" difference in their heigh but spot on for weight. I love to watch them grow.
