Hi everyone! I was wondering about using a double stroller for my dd and ds.Ds's cardiologist wants us to use the stroller as a wheelchair,and have the GAC stamped for that.Can I use a double stroller?My dd is almost 7yo and will need one,so I wanted to use a double so I only have to keep track of one stroller instead of 2.The stroller I will use is a side by side,a Maclaren so it fits through standard doorways.Anyone know if we can do this?Thanks!!
