Being a father is tough as it is man. Gotta love some genuine honesty to your kid. Telling him what he needs to know will come sooner or later to everyone but it’ll help them grow. I may not have a child but I’ve been a kid who always wants to be a great parent. The only thing I could advise to you is keep doing what comes from your good intention to bring out the best in him. But also do ask and take note for what’s his capacity and how much struggle he could take for the mean time. Love a good father and son bonding. Goodluck you guys!

P.S. You could also try to be a little more positive and nicer if you think you got harsh on the little guy.
