Hi J.:
I was wondering if they would like to do activities together like color with crayons, do some puzzles, or something along those lines just so the 4 yr old can start warming up. I have a 19 month old, he loves to color. We bought a roll of paper, roll it out and tape it to his table and chair set (underneath the table) and he just draws on the table. (Just like you would at Bravo's or something.)
Let us know if you find something else!
