During the winter, if weather permits, you basically need to just go outside anyway. Don't let snow stop you from doing things. Take the picture above for example. Snow everywhere, and yet swinging is still fun. Don't think the only things you can do in snow are sledding, building snowmen, snow angels, snow sculptures, or snow forts, etc.
There will also be times the weather changes for you for a day or two and you can do something like go for a walk! This year was literally the first time I have taken a child of mine on a walk in January. The winter before Kaitlyn was born, it would have been possible, but I have this mental block in my head for certain temperatures so Brayden and I never went for a cold winter walk. After a long, cold winter last year, I decided this year I would take advantage of any glimpse of nice weather I could get.
It warmed up to the high 40s, which a few years ago would not have been walking weather in January in my opinion. But the day was sunny with no wind, so I dressed my girls up and we went for a walk! The sun shining on me felt so good, and I felt this renewed energy! I was ready for anything that day! I also ran into other moms out with their kids who had the same idea I had: get out while you can.
So if you are like me and get a mental block in the winter, try to step out of it. Play with your outside toys when you can. Go for those walks. Fresh air and sunshine are so good for you physically and mentally.
Spring time is approaching (faster for some than others). I suggest you decide now that you will be flexible and get out on any nice day you can. Just be ready to spontaneously put things off to get that outside play in when that nice enough day comes along.
For those of you surviving rainy seasons, think of ways to get out and play in the rain. Get appropriate gear so you can be comfortable and have fun outside! Outside play does not have to be reserved for 60-80 degree weather.
