Toddler activities?

I just started watching a 2 yo, I also have a 2 yo. They're both super independent. I've set my days up to be with them all day, no distractions but now I don't know what to do with them lol they just play together or independently and want nothing to do with me unless they're hungry 😅 we go outside, read books and do crafts but I feel guilty being paid and not really doing too much.
