Has it snowed in your area yet?  Getting outdoors when the sun is shining can be the best thing for your little ones (and older kiddos too!).
Last year I took AJ sledding after preschool several times a week just to get his “wiggles” out and it did wonders for him. It is a great proprioceptive workout for kids and the slopes are empty on weekday afternoons.
Just watch out for those icy spots…I broke our saucer on an ice patch (and hurt my bum!).
