If your smallest child - who also happens to have significant delays - exclaims Oh Shit when something doesn't go her way, you have probably committed a parenting fail somewhere along the way.
Speaking hypothetically of course.
If you and your other children hear the above exclamation and burst out laughing you have probably just compounded the fail.
When discussing your broken tooth with your dentist, the expression "I cracked a root!?" is probably not the best one to use (in Australia anyway - that fail may not translate overseas).
Anyone else got a fail they'd like to share??
