Off topic: I had the exact same idea for a site, except a darker version. It was going to be thisfuckingkid.com and would be a collection of quotes, just like your site, but that all had to start with "This fucking kid...". I nearly registered the domain at 3am after a few sleepless hours of bouncing on an exercise ball trying to soothe my daughter when she rewarded/tested my patience by biting me instead of falling asleep.
