It's called the Rapley methode, or you could 'google' baby-led weaning.

I did a lot of research about becoming a mom from when I was 14 years, since I loved biology and I just came across it one time :D

As a mom, I wouldn't think I'm original at all xD
As for original, have you heard of Priscilla Dunstan? She had such good ears that she 'invented' 'discovered' that babies have their own universal language based on sound pitches (!)
