Im a mother of 3 girls, im pretty much by myself with them. So i can understand. Im not sure how old your brother is, but have u thought of doing anything, like walking to a park, or if there's any ice cream stores around. Do u have public transportation, maybe a library. You should look up free event in your area. I think the biggest issue is trying to find something to do to keep your sanity and his. I know kids have alot of energy, so maybe something to help him burn so of that off. What about building a fort, or making a mini waterpark in the yard. I hope things work out for ya, best of luck
