Breathe in fresh air, find a place for the kids to climb, find another lonely mom to talk to, and take in the remarkable beauty of nature.
Gather acorns. Take them home to paint. "Feed" the geese with dried up leaves. See who can swing the highest. Laugh at their silly jokes.
Walk away from the news.
Look at the small things like the veins in leaves.
Refrain from being overly protective. Let them have fun.
Don't worry if someone overhears them and thinks they are weird.
Let them make a few messes.
Messes are easier to clean when they are happy. Be thankful. Be happy.
Allow yourself to enjoy life. Teach them to enjoy it, too.
