Greetings friend,
Seeing how vividly you demonstrated how you discipline your younger ones at home, I couldn't help but smile as they made me reminisce about my childhood.
But I hope it was done with love as brute forces would only give them the impression that you hate them rather than them seeing you correcting them for their wrong deeds.
I was once like that, till I grow to realize it was for my good and I've been thankful to those who disciplined me the right way with love. All the best my friend, Good luck.
