My wife and I are going to Disneyland and taking our 3 year old granddaughter. Problem is I need to push my wife in a wheel chair. She won’t use an electric one. Too dangerous. So how can I push my wife and stroller at the same time? I have read that you can not sit on ones lap in a wheelchair you are pushing or is that only in regards to an electric one? Please give me advise. I can’t push both.
