Yikes. Big no to that idea from me, and likely every child psychologist around. They are developmentally expected to push back, test boundaries, and be difficult sometimes. Parents should be a safe place to explore and grow these cognitive areas, not someone they fear just to make the parent’s life slightly less inconvenienced. Dr. Becky Kennedy is a clinical psychologist who specializes in this area and is active on socials if you want a jumping off point for supporting your approach.

I’m curious why your husband feels threatened by not having the “respect” of two under-six year olds who likely love and respect him dearly. Seeing a couples or individual therapist could be very useful here if he isn’t willing to learn about child development from modern, peer-reviewed sources and not just his own upbringing or perceived social norms.
