I hope I'm not about to be spit roasted here but...
I took the beloved dummy away from DS when he was about 2.5. He's just turned 4. But he got croup over summer and when he cried (which badly aggravates croup) the best way of stopping him instantly was giving him the dummy. So he's now back on it, for sleeping only of course. It's just such a relief for him, like flicking the off switch and he's asleep within five mins.
But are there any reasons I should force him to stop again? Is it really bad for his teeth?
