Quick question. Does the word kind come from the German "kinder" so in essence child like?
Short answer: no. Long answer: They might be related, but I'm not sure. 
Kind comes from the same root that gives us 
kin and, via French, Latin, and Greek, a whole host of words like 
genus, gene, gentle, general, and 
genius. They all go back to a Proto-Indo-European word meaning "to beget" or "to produce". 
With 
kind, the sense developed something along these lines:
natural, native
belonging to one by birth
of good birth
having good qualities
having a gentle or nice nature
From what I can tell, the German 
Kind is related, meaning it descends from the same root, not that it was borrowed from English or that it was a source of borrowing into English. The etymology there is a little more straightforward; the Proto-Indo-European root means "to beget", and in a sense the German 
Kind means "one who is begotten".
