I know exactly what you mean! My 5 year old is suddenly 21 and graduating U MD this upcoming spring semester. Where the hell did all that time go?! You really do look back on the "old times" which were fun and really do miss them. Can't get it back of course, but as long as you keep them in your mind and your heart (and many photos!), that's what matters. I have a picture of her during the December 2009 storm (she had just turned 6), with the snow nearly up to her waist!
