I'm trying this with the money is no object theme that James used. And I'm doing alright. I'm not fretting that they're all attention hungry little monsters, and that they don't want to have fun without me. Meh, little boogers.
Instead, I'm focusing on teaching them potty skills, being fed, and bath's when needed. The rest is on them. I'm even not afraid to keep sleeping when they wake up because I prepared myself and stuffed a tray in the fridge for the morning. ;)
Heartless? Maybe. But it's working quite well for me. ~.~
