Render issue using context api in combination with render props

[ifahrentholz]

Hi @kentcdodds :)

I've started to work with the context api in combination with the render props pattern.
Unfortunately I'm running into an rerender issue..

For example I have 3 inputs and only change one character in the first input field. That's causing the whole form & all inputs will rerender.

Do you know some way around this issue ?
