Assuming you have a garage large enough to store a stroller, the best way to store a stroller in the garage is by hanging it on the wall. This can be done with either specially made hangers or by simply attaching hooks to the wall. If you don't have a lot of space, another option is to fold up the stroller and store it in a bin or on shelves. Whichever method you choose, just be sure to keep the stroller clean and free of dust so it's ready to go when you need it!
