Poor kid! I had a hard time sitting still when I broke my foot - as an adult!
Well, not that I've been through this with my toddler, but try doing crafts. Painting, coloring, working with glitter and stamps. Make a sticker board. I'm sure there are great ideas online. Color Easter eggs. Who cares if Easter has passed - celebrate it again. Perhaps you can come up with a "fishing" game he can do from the couch. Hmm. Maybe have him scoot around on the floor and mop for you? Perhaps that won't hurt so much and get him moving a bit. My baby's crying. Best of luck to you!
Oh, and the period coming back - totally normal! Don't worry about that.
