Daddy, Im having trouble breathing.
Sure, that’s how four year olds talk. Has he ever been around one?
Daddy, Im having trouble breathing. I don’t think so-—I’m sure his kid said “father, I am experiencing respiratory distress.”
Good point. Four year olds don't say "I'm having trouble". If she said it, and she didn't, it would have come out like "It's hard to breathe" or "I can't breathe."
