I think not, they are kids, they are happy, they are developing well. Don't mess with that and muddy things up!

IMHO the best prophylactic for mental health in children is healthy, caring, loving parents who respond effectively to the changing developmental needs of their child. Take care of your own mental health and actively work on developing and maintaining both your own parenting skills and your relationship with each child. If you can be their sure shelter in stormy weather all will be as well as it can be.

Children don't want a stranger to talk to for one hour a week. They want to know there is someone in their world who loves them no matter what and who they can rely on no matter when.
