I don't blame this poor husband! My son has never slept in bed with us other than special occassions, like watching E.T. or Star Wars with us while we were all snuggled up. Needless to say he was put into his own bed once he fell asleep.
As for this being an "Asian Thing", I am half Asian and no one in my family with children lets this sort of behaviour become a habit. I actually know many people who do let their children sleep in bed with them and in the cases of these families, the reason boils down to pure laziness...not bothering to read stories at bedtime or wanting to teach their kids that they must learn to sleep alone... I have often wondered whether these mothers do it for the children or for their own selfish reasons
Don't even get me started on the breastfeeding issue!
