My dad is very strict with my kids.
Sounds like he has a strict view of parenting. It will promote the emotional and social development of your children.
Yes, but he just wants them to learn discipline.
He could use the Positive Discipline model which focuses on positive behavior.
Yes, I have no issue with him helping.
That's good to hear. Child discipline prevents future behavioral problems so it is important.
Hopefully my kids will not have behavioral problems.
I am sure they will be fine. As long as their care takers display good parenting skills they will be fine.
I think I have good parenting skills. I guess time will tell thou.
True enough. Child development is dependent on developmental experiences which can be hard to predict.
