I'd say one of the most important things is missing... read to them. Tell them stories, engage with them. build Duplo with them, draw stupid stuff with them.
I dislike the opening though... a high sense of discipline is not something that a parent should be seeking in his children. Teach them to trust and understand you, it's far more productie, and obedience will come natural.
And not too much of it.
thank for your comment.. ☺
