I have the audible version of Parenting by the Book, which I love & has been very helpful. In one part of the book Dr. Rosemond gives a few simple explanations that are ok to give to children, along with “because I said so” (six maybe?). They were things like It goes against our family values, etc. I can’t find that section on the audible version, could you please recap them for me? & is there an age under which they should not be given? I have 3 year old twins. Is this too young? Thank you.
