Liam has always been responsible for contributing in the household chores. He is responsible for keeping his room clean, helping to clean up the playroom and odd jobs around the house. This may seem pretty standard to most, and honestly, it is standard here too. We just require a little more planning. Since bending over to pick up items is really hard we have purchased a grasping wand. Liam scoots around the room, puts everything in a bin and then I pick up the bin and put it on a table so that he can put things away from that point. It eliminates the challenge and allows him to succeed and be a helper. 
Liam has been asking for a way to earn money so that he can collect even more pokemon cards to his collection. His summer job is to do the unpleasant task of picking up dog poop. We have a big dog, so Liam has plenty of work! We purchased a pooper scooper that Liam can use without needing to bend over. I can see how proud Liam is of himself when he completes his work week and puts his crisp five dollar bill in his piggy bank. Hard earned cash, for him to spend, save or give as he pleases.
Mark and I expect him to know that he will work. He will be a helper. He will find a way to get things done. With a little problem solving, a bit more planning and some helpful tools he can do anything he wants!
