Green Toys Stack & Link Racers

My 18-month-old loves how these cars stack into a tower and then knock them all down—the linking mechanism is simple enough for her little hands to snap together on her own. They're surprisingly sturdy for being pocket-sized, and I appreciate that they're safe for her to chew on.

These little cars link together easily, which is great because my toddler loves pulling a whole train of them around the living room. The size is perfect for his small hands, and they seem really sturdy for all the crashing they endure.

My one-year-old grabs these little cars with both hands and giggles every time they snap together or roll apart, and the size is honestly perfect for her grip without being a choking hazard. We've got them scattered across the living room floor now, and she's figuring out the linking part faster tha
