Just wanted some opinions/experiences on when might be a good time to try to end the dummy. DS is 2 and a half and uses it for sleeptimes only. We are soon to move him from his cot to a bed and I am guessing the transition will go well as he happily sleeps in one at his cousins house. So, I was thinking of selling him the idea of big boys in big beds don't need dummies. Do you think this is a good idea OR do you think that's too many changes at once??
