Question for seasoned SAHMs

After your toddler/young child stops napping during the day, how do you get “alone time”? He doesn’t do the quiet time people always suggest...he hates books, and is very energetic, constantly. Now that he doesn’t nap I’m finding myself so exhausted by 6pm that I can’t even make dinner. I also have a 1 year old but he naps for a few hours a day. My 3.5 year old though has dropped his nap and I don’t know what to do anymore. I used to love that hour where I could eat and watch tv in peace. I don’t have it anymore. 😭
