I consider every child I serve, unless they exuberantly tell me if they want apple or orange juice, to be non-verbal.
I don't think ordering at a restaurant is a great time to teach your kid to talk. It's a simple choice: apple juice or orange. I hate it when I'm fetching my beverage order and the parent asks the kid what they want to drink and the kid says nothing.
I have to stand there, encouraging the kid to answer my question, as if I'm a freakin' teacher or something.
Look, lady, you wanna teach your kids to talk? Do it on your own time. Thank you!
