Our eldest is about to fly the coop to leave for college and our youngest had just started walking well when I took this picture last year. One of the nice things about being "experienced" parents is that you learn what's important and what isn't. You don't waste your time or energy on non-essentials. You appreciate tiny but amazing moments of beauty and joy and you savor them.
If you are a new parent, take the time to get to know several older parents. Watch especially those whose marriages you admire. They may not have homes that are immaculately clean. Their flower beds may be full of weeds (our is!). But I bet they have a sense of humor
