It isn't a 100% guarentee, just like everything in life, but it did work wonders for us. DS is now happier playing alone too, before he wanted me to join in constantly, and now he just needs me around generally. While needing Mama wasn't something I wanted to fix, or even thought was wrong, it is quite nice I can sit down or talk to friends in the park and he'll play for 10 minutes or so without needing me.
