Re: In our house there is a monster.
Have you thought of rationing the toys that she gets? If someone brings a gift, perhaps you could put it away for another day. It might be a good idea to talk to the gift givers and explain what you are trying to instill in Safia.
This is not really related to the topic, but I thought I'd suggest it as a way of controlling the number of toys in your house. I was watching Nanny 911 and in one episode, Nanny Deb convinces the kids that they have too many toys and that it would be nice if they could donate some of the toys that they do not play with to charity. She also created the one-in one-out rule. If a new toy comes into the house, one toy must be given away.
