When they watch, listen and work with him they learn so much! Every time my husband is working on a project I send my children his way. I want them to learn everything he can possibly teach them. This weekend they worked together to build a frame for my swing for the backyard. Spencer was the numbers guy and Jake was the helper. All four children watched, listened and worked with him in some way or another. My husband loves to do projects like that especially with his children.
