My dad is head of ENT at a children&#x27;s hospital in Sydney and goes on a media blitz in the weeks before Christmas on tv radio and newspapers warning parents to keep these batteries away from kids.<p>It&#x27;s a real problem. Every year he removes these from little kids. They&#x27;re a lot more dangerous than almost any other foreign objects that get stuck because of the electrolysis causing caustic soda.<p>Be vigilant with your little ones and their new toys.
