Sharli and I had a Saturday afternoon to fill while our guys went fishing. I wanted to bake some bread, but wasn't too excited about little fingers "helping". I put Sharli in her highchair and sprinkled some flour on a cookie sheet for her to have. She thought it was great!
coin cleaning activity a few days before and let her see what happened with that.
Here is Erik doing the same thing when he was little (also while I was baking bread...).
