I read a book by a professional nanny and she believed that the behavioral individuality that you would find in babies already at a few months old (liked to sleep a lot, often grumpy, often giggly) would follow them to adulthood. I think there's some truth to that.
That sounds logical to me. I was just pointing out that the headline is linked to a Nature article that is specifically about fish (genetically identical fish) which makes it considerably different than what most people would assume from the fish-less headline
Oh, that's a good question. It's been a long time. I'll do my best to find it but I very few memories about it, other than what I mentioned and that the premise was (in part) to nurture your child based on their personality. It was actually one of the best books I read when my daughter was born, so I'll really try to find it for you.
Edit: I think it's "Secrets of a Baby Nurse," by Marsha Podd. (Maybe. It's been a long time.) I hope that's it because so many of those books were uninformative or simply reassuring (e.g. "Yes, it's normal ..."). This one talks about how your baby is communicating with you from the start and how to watch for that to make both of your lives easier.
As parent I’d agree that there was some innate behaviors and individuality of personality that persists from the start. No idea how to quantify it but have witnessed it.
