Hey Sara,
We were talking about this in mothers group the other day. Some mums had heard of the technique where you get your bub to swap the dummy for something else they want - ie, literally getting them to hand the dummy over to the check-out person in the shop, in exchange for a toy or something (with you obviously slipping some cash to them as well, LOL!). Also leaving the dummy out for Santa to take away was suggested (if you can hold out til Christmas?!) Or making a big deal about throwing the dummy away on a particular day, having your DD put it in the wheelie bin herself, and then using loads of praise. The rubbish man then is the baddy for taking the dummy away, not you.

But as you know, my DD is still very young and I have no experience with a 17 month old, so I'm probably no help!! My DD uses a dummy for getting to sleep, so I am sure I am going to have to deal with weaning too sooner or later.

Good luck!!
