I have a 10 month old, an 11 month old, a 14 month old and a 2.5 year old. The 2.5 year old plays alone for about 5 minutes and then comes over to me and says I'm done! It drives me nuts!! How do I get him to just go play? I know the other kids are younger, but they can still play with him. I have PLENTY of toys outsides, and plenty of room for them to explore. I feel like I'm always saying "go play". I go play with him a lot - we have morning nap times together me and him, so he has a lot of my attention, but during outdoor play, specifically, between morning nap and lunch, he won't play alone. How do you do it??
