My 10yr old daughter does not have any friends her age. The only children that she plays with are at least 4-5 yrs younger than she is. I try to get her to play with other children her age, but she can be very bossy and gets upset when she is not the center of attention (we are working on that...) Should I encourage her to play with the younger kids? She is not very socially mature, and I am sure that is playing a role in this, but wouldn't playing with younger kids just promote this? Wouldn't playing with kids her age help her develop maturity?
