Usually?
I have a 6 you who is very bloody minded determined! She is growing up now, so I think I should no longer "dictate" about certain things - clothes, activities etc. (Obviously for some things I am keeping foot firmly down - sweeties, safety, sleep etc)
So in this spirit of fostering independance, where do you draw the line? For example:
If you KNOW that the new sandals will rub if she wears them without socks, but she insists they are fine....
If you KNOW that if she takes her lastest Littlest Pet Shop thingy to school it will be stolen/borrowed/lost....
If you KNOW that the bag of "essential stuff" she insists on bringing on the family day out a( isn't essential b) daddy will end up carrying it
So do what degree do you insist that they DON'T do these things vs telling them it is a bad idea and letting them find out why....
