You're wrong. Babies are born with personalities. They have them in the womb too.
& there is a such thing as spoiling your baby. I spoiled my cousin. When he got sleepy, he would only stop crying & go to sleep when someone would pick him up & rock him to sleep.
Babies are kind of boring until they learn how to crawl.
Cheat on her, destroy your family and be put on child support? Not a good idea.
I'm sure you know more than the scientists who make studies detailing child care. You got your PHD, in what?
Personalities, my ass. They start properly expressing those personalities at 6-7 months in.
