We have a stroller issue that I am hoping that someone out there may have suggestions for. I have two children, ages 5 and 4. My 4 year old has muscular dystrophy and struggles to walk long distances. And our dr. has said that he does need to ride a lot so that he doesn't wear out his muscles. We have a joovy tandem stroller that we have used for a long time. However, his feet are not protected as they get caught in the wheels and he is about to grow out of the seat. We are planning on doing some traveling this summer that will require lots of walking (a few amusement parks, museums, etc.) and don't know what to do. We have a single stroller that we like for my daughter. We don't have anything for my son. We have been debating on whether to go ahead and get an expensive double stroller that has a higher weight limit for my older kids, get him a push chair if we can find one relatively cheap that will last a year or so, or just get a regular single stroller and attach them. I have to make a decision soon but am really stressing it. I want to make this a fun trip and there is no way that either of them can do the walking AND enjoy it. Any suggestions from others out there?
