A free and easy busy bag idea for your toddler: paint chip matching!
You can pick up a few of these at your local home improvement store. I chose basic colors in the larger size. After cutting each one in half, your toddler can match the colors through the little square windows, which is surprisingly entertaining!
Since this busy bag is so compact and fits nicely into a plastic sandwich bag, it is great for slipping into your purse when your little one is getting restless or bored. A helpful hint: laminate each card for durability!
