Imagine doing this for 6 months?

... Instead of whatever it is you're doing right now. You reallly, realllly need to have a patience for children.  Most likely someone who absolutely loves kids and thinks they're adorable when they do horrible things and talk in their wee voices all day.

So if you're one of those kinds who doesn't ever plan on having children, never-ever consider this as a job! Because you might not love it as much as we do, clearly!
