I have been trying to recreate that with Logan.
I got a bucket of buttons from a craft shop, put them in a tupperware I had and let him pick out a set of measuring cups when we were at the Goodwill one day.
Today I asked him to find me all the blue ones (one of the 4 colors he knows on site):We did that for about 15 minutes... with him asking me "Dis blue one?" and me saying yay or nay and then him putting it in the cup. Then he decided that we needed to use the little cup:
Alas... the little cup doesn't even fit one button. lol... but he sure did try for a while.
