My fiances 5F little one will not drop the binky habit...like would have it in her mouth ALL DAY if she could. I've never seen this and her mom/grandma continues to pack one for her when she sleeps over like I feel like a monster telling her no but it enrages me. We don't want to traumatize her by taking it but like at what point do you draw the line?? If she forgets it here I throw it away but they keep buying her more. They say they dont stop her because they don't want to "deal with her screaming". What do?
