You know you're a parent when...

You get used to drinking cold cups of tea

You refer to yourself in the third-person (eg. Daddy is going to read you a story)

7.30 is considered a "sleep-in"

Everything is half-completed: You eat half a meal; wash half the dishes; and only watch half a movie

You forget to sign out of internet banking

You look like a nutcase humming along to Heads, Shoulders, Knees and Toes while standing in line at the supermarket
