Cooper just turned 3...and is wanting to learn learn learn! I don't do anything formal with him, we just do as we go. I'd love to have some kind of a resource book, yknow? Of truly age appropriate activities, lots of "doing", manipulatives etc etc. I'm running out of activities fast! (and not to mention I have been mega-tired these days adjusting to having this new babe). I looked in the rainbow resource catty today, but I don't recognize any of the names etc... TIA!
