Spart Teens and Spark People are kept very separate.
I'm not sure about recipes - maybe if they do both use sparkrecipes.com then recipes shared on there would be accessible, but likely not manually entered food items.
You cannot hook up as 'friends' or connect in any way.
They do this to help protect the teens. You're just wanting to connect with your daughter, but you wouldn't some pro-anorexia person hooking up with her and feeding her incorrect information about healthy weight loss.
