We has big problems with the dummy. Frist time we went without dummy we went out & a little boy walked past us with the same dummy in his mouth so my DS1 took it out of his & went to pop it in his own mouth, lucky the other parents could se the funny side in it.
We tried Santa, & put up with the crying till he got chicken pox new years eve & gave it back.
Our last try was we got him to put it on the door step for the baby bunnies at easter, & in return they would give him a present, it worked. Every time he saw bunnies he asked it that was the one that got his dummy.
I have learnt over the years & 3 kids later not to get hung up on dummy's, bottle's & toilet training.
Do what works for you & good luck
