How about Brittney Spears as a partner and guide. This idea is child endangerment. Best case: He's 3.5 yoa--he will not remember anything other than the comments you direct toward a photo years later. Worst case: something happens and you have a fatal outcome. I treat children with disabilities every day. If you want quality time: fly a kite, backpack through old growth, go to the beach, swim, play lego's, read with him, etc...Who's to say he won't be kicking steps with some awesome prosthetic limbs in a decade--if that is HIS choice.
