mei,
I saw the news on TV yesterday. Hao Re has the OSIM fever band. And we let him used it then bite on it before. Thank godness that time he still has no teeth, if not... gosh, don't want to think about it. Have thrown that into bin.
Wonder if the coolent filled in the teether might have gylcol also? To play safe, I won't let Hao Re use any of these things filled with liquid, unless I know what it's in it.
