Five.

Dear Tess & Oliver,
Five years? How can it be? I should be planning a big party to celebrate the fact that you are each a "whole-hand old" now.

1,825 days plus 1 for leap year, that makes 1,826 days without you two.
Not one of those days has passed without me wishing you were here.

Sigh.
Much love my sweet babies.
Mama
