Our kids keep us so close, I have found it very hard. When our 6 year old daughter takes each of our hands, pulls them together, squeezes them between hers, and looks up at us with a sad longing expression, detaching is pretty dam* tough.
Damn, that broke my heart.
All the more reason to stop doing what you've BEEN doing, and try something stronger/more effective, even if it's damned difficult.
