Definitely take time to remember for they are gone quickly. I sent my oldest back to college today and am feeling...I don't know. Sad, fulfilled, not needed(except for money). Keep those memories close, because at moments like these it is very heartwarming. Sit and watch the sunset with them, read stories every time they want you to, play with them even when you think you are too tired, but most of all just show them you love them.
