Nell and Delia have gotten together for a “Mommy Meet,” during which they have coffee and chat at their homes. Today they both have their 18-month-old sons, Steve and Nash. While the ladies sip and chat, Steve and Nash crawl around on the floor pushing toy trucks and making “vroooom” sounds. Every now and then, they switch trucks with each other. Steve and Nash are engaged in ____ play.
