My 2 older kids had them & ditched them around their second birthdays. DS2 refused to take one, and Pie has one but I try to keep it just for sleep. I have noticed as she gets older though she's more prone to picking it up & sticking it inher gob without thinking about it, if I see her do it I will take it out (if she lets me, lol)... having said that, it's never really been an issue here, they all drop it eventually and they can be an absolute lifesaver!
