My DH is in charge of cutting the grass, but he has been working long hours and helping out in a million other ways when he gets home. This time of year it really needs it a minimum of once a week, but ideally every few days because it grows so fast and he just doesn't have time to get it done. I can leave my daughters in the house to get it done, but definitely not my almost 18m DS. I would never let him play outside while I mow, but I am wondering about wearing him. Is there any reason that wouldn't be safe? I guess flying objects could be an issue, but I would be between him and the mower if he is on my back. Anything I am not considering? I would love to surprise DH by taking something off his list of responsibilities, but not at the cost of DS's safety.
