Babies... 3

One thing I constantly see/hear is people raising their eyebrow when they hear some of the things I consider good for child development. Playing with my kid upside down for example.

But, then there is this great book... at least the first half is great...

Daddy needs a beer

An average dude with average income wrote it. It's funny as hell (for the first half). This dude basically writes about all the fucks he didn't give when it came to raising his kids, and they seemed to have turned out alright.
