Hi! I am blind and my husband uses a wheelchair. Here are some things we have done with our 2 year old and 4 year old daughters. Our youngest daughter is a runner. Last spring she took off with me and her older sister in hot pursuit! I did not enjoy it so here is what worked for me. I got her 2 of those kids stuffed animal backpacks. They each had about 3 foot long leashes attached to them. She really liked them! I let her ware it around the house for a few days. Now when we go out, she wares her backpack and I either hold the leash that is attached to it or she holds my hand. Both my girls love going for rides on their Dads lap as he drives his power wheelchair. This system works well enough with our girls that we independently take them on adventures using public transportation. our girls particularly love to go to a local children’s museum. I have found that there are a few rules that I am very firm with even if it means a massive temper tantrum. For me, I need to know where the kids are at all times so I know there safe. So for example, when we go outside or go to the kids museum they have to respond to me. If they don’t we leave! I hope this helps.
