Babe, I don’t know. But based on what you are saying I can’t see any evidence of a cardiac event if there was no actual diagnosis and no basic follow up.
An ECG is your first line cardiac assessment. Second is a TNI.
While your BP was high, given the situation that would not be overly concerning.
Children thrive on praise. At our core we love to be complimented. If your boss tells you you’re doing a good job you work harder.
For every “no, that’s naughty” try and give 10 “good listening” “good sharing” “good boy”. Good breeds good, and naughty will breed naughty. I was raised to be a naughty girl, who didn’t listen, was a sneaky little shit house rat, and needed a good smack and that is exactly what I became. I got yelling and smacks. Takes a good decade to undo an unhappy childhood.
Communication is the key. They are little sponges. They soak up your words so choose them wisely.
