childless, cynical male
It shows

I hate to play the "you don't understand unless you've got kids" card, but in all honesty, you just don't understand how hard work it is until you've experienced it - I was the same.
I love spending time with my little boy, but I look after him all day over the weekend while my partner works, and it's a nice break to get back to work on the Monday!

Now he's only 18 months, so he needs watching like a hawk - I'm sure when they're a couple of years older they're not quite as intense, but it's still not the easy ride you're making it out to be.
