Ooh, a friend of mine was brought up by her Dad from when she was about 3 and her sister about 5. What's interesting is that my friend was totally happy with how she was brought up - they were pretty much allowed to do what they wanted, like, sleep in different places around the house, etc. and their Dad was a cool guy - odd, and history-buff geeky, but cool.
But the sister blames their Dad for everything that's wrong with her life - for not making sure her hair and clothes were tidy etc. when she was a kid, and letting her go out in a state where presumably she got teased about it.
My friend is a brilliant mum, and her sister - not so much...
