I have to say I am the exact opposite, I dont think you can "spoil" a child either, but getting up at night made me crazy, I need 9-10hours of sleep. Anyway, I let both of my kids cry it out, and it was hard, but they do not wake up anymore. My 4 year old gets up once in a while to go to the bathroom, but that is it. I am not heartless or mean, I just need my sleep.
