@ DJLN description of Boys vs Girls. Perfectly encapsulated my 2 kids. I thought my girl was kind of wild and crazy and then that damned boy happened. I keep telling him, "Head not hammer". Little ****er burns pretty hot.
As far as bonding when they're young, there is to that, but I didn't have quite that harsh of an experience. What was unexpected on my end was how much easier to the first 2 months vs when they get going a little bit. In the beginning, unless they have colic, it's just a matter of keeping it fed, changed and slept. After they figure out that they want things it gets tougher. Then when they figure out object permanence, life starts to suck. I was expecting the first couple months to be tougher.
