I see no reason to take it away, but I would start telling her since shes a big girl, that her pacifier is just for in bed. Just nap time or bedtime, but not out of her bed. If she chooses to go stay in bed with it for a while thats fine, but she will want to go do other stuff and will leave it behind. She may even run back now and then to get a "refill of suck" and then run back out to play. She will eventually have enough stuff to keep her busy to not need it. Dont worry about it with a new baby coming but dont buy her any more either.
