I always remind beginning NLP enthusiasts that NLP is all based on things we're already doing naturally. It's just that a bunch of very clever people took the time to really observe what was going on and codify it for us to use.
Turns out, even newborns are savvy to calibration and rapport techniques!
Researchers at University of Würzburg in Germany have discovered that newborn babies from different language-speaking groups cry in the same vocal patterns that their parents speak in. So babies form French-speaking households cry in French vocal patterns, and the ones from German speaking parents cry with German tonality. (Ach du libe!) Said one of the researchers: "Newborns are probably highly motivated to imitate their mother's behavior in order to attract her and hence to foster bonding."
In NLP lingo we'd say they're calibrating the mothers tonality and applying rapport techniques to foster the bond.
So easy a child could do it!
