My dd has just given up her dummy - 2.2 years old ...
i just went cold turkey!!!! To be honest it was WAY LESS difficult than i thought it would be. I just kept telling her, you're a big girl now ... no more dummies
i also let her decide (in the middle of a teary first late night) that she could have a chocolate egg and an umbrella (I'm not sure she got the whole exchange thing, but she sure was excited at getting an egg!!!)
The first two nights were the worst (think back to those teething nights, took about 1-2 hours to settle her) - by third day we were over the worst.
I bought really nice snacks to give her when she was in the pushchair - this also kept her from asking for a dummy
It has been a week, and was so much easier to do than i thought - just give it a go and see what happens!!!! Once you get over the first night (I started the cold turkey at night) you realise it can be done, and i felt empowered to just get it over with ...
She has occasonally asked for it, but more in the way they ask for juice, or a treat - not really expecting it, just trying!
I honestly thought it was going to be really difficult and had put it off for months ....
good luck, let us know how it goes
