My DS is 25 months and has really had a mental growth spurt in the last month or so. He plays pretend constantly and is very creative. For example, tonight he was pretending that his black beans were family members. Then he was putting all of his trains into a play barn and laying them down and turned off the light. He said they were sleeping. Then "woke" them up. It's all the time with a new story.it's so cute and fun that he likes pretending like this now! When did you notice this change in your LO's play?
