Hi Tia,
Unless you truly are an outdoor person who thrives being outside, I think most moms feel as you do from time to time.
I, too, struggled with these feelings when my daughters were younger. But I knew how important it was for them to get fresh air outside, so I got as creative as possible in dealing with my boredom/discomfort out there.
It has paid off, because now my daughters are very active, and love to play outside, and because they are older, it is easier to let them play out there while I keep an eye on things from inside. And sometimes I still join them out there, because playing outside has begun to grow on me, too!
1. Remember that they are only this young for a very short time in the whole scheme of things. Once your son gets older you and more independent, you won't have to be hovering around him making sure he is safe every second. At this age, this is a drag, but it can be fun, too, in the right circumstances. So know that as he gets older and makes friends at school or in the neighborhood, he will have a buddy or two to play with, hopefully sometimes in their yard as well as yours.
2. Obviously a fence is a major expense, and your neighborhood might not even allow them, but it is something to consider as an investment, especially if you are going to have more children.
3. Get to know other moms from your neighborhood, church, preschool or work, and see if you can set up playdates. This should take the load off for 1/2 of the time.
4. Take up a hobby that you can do outdoors while you are watching your little one at the park or in your backyard. I would knit, read and write letters while my little ones played outside. And, of course, going with a friend helps and you get adult conversation as a bonus. You can always make phone calls, too.
5. When the weather is rainy, snowy or just plain rotten, we found a great solution that gives them exercise indoors. We bought each girl a mini trampoline. We keep them under our bed or in the garage, and pull them out all the time. They still use them. It helps them let off steam safely (because they're small). And they're only $30-$50, which is a small investment for a lot of entertainment and exercise for them.
I'm sure there are many other great ideas out there that I haven't even begun to think of. I would actually love to hear some.
There are also computer games (when he gets old enough) that incorporate more physical activity into the3 computer experience.
I have to say, though, like several posters have mentioned, outdoors is the best place for them. For the last 2 years, I also take walks with them in the neighborhood for about an hour before bedtime. We talk, point out things, and get to spend a lot of quality time doing this.
As you can see, things have improved for me since I was a stay-indoor SAHM. It was worth the extra effort, and I have benefited from it, as well, by losing a few pounds along the way. You and anybody else can do it, too. It's always hardest to change former habits and ways of thinking at the beginning.
Blessings to you and your family
