I believe that a child should know that s/he is loved by her parents, unconditionally. No matter what s/he does and says.
Well, this is a great bedtime book especially on those days when they need a bit of a reassurance.
From the book:
Alex Bear has broken his mother's favourite honey bowl.He didn't mean to- but he knows she'll be mad. "Will you only love me if I'm good?" he asks her. "I'll always love you" she replies.
