I don't know any reason why you can't cut grass while pregnant - on a riding lawn mower or any other kind. As far as leaky breasts, that is perfectly normal and is generally to be expected especially at first. I did find something that works well for nighttime though because wearing bras to bed is uncomfortable. Target sells maternity tank tops that are very comfortable to sleep in and make it easy for those middle of the night feedings. You can put breast pads inside the tank top to help keep your sheets clean. You can find them at Target in the same section as their nursing bras. Other places may carry them as well. Hope this helps!!
