Terriamn. I use 2.5" squares for I Spy quilts but it is really up to you. I am a bit partial to 2.5's
Often folks think that little children need to have larger blocks but that is not true. Even itty bitty ones, can spy a crumb on the floor and pop it in their mouth. It is also good for them to begin to discriminate small identifiable objects, shapes, and colors. More important is what size do you want to use and have on hand. Have fun and use those squirrels.
All, I found those little squirrel last this summer at one of my favorite quilt shops in Shipshewana, Indiana. Just could not pass it up.
