I like the idea of a lollipop using paint chips but I dk if I'd ever make a card like this though. What an adorable use of a circle punch! Paint chips would be great to punch for these, just pick your favorite colors.
When you're in a busy parking lot use a "safety spot" on the side of your car while you unload the stroller, etc. Your child should place their hand on the safety spot and not move until you tell them it's safe and they can hold your hand.
