Boots have just written to notify me that they're recalling their Penguin & Whale teethers because they contain higher than normal levels of sterilising solution. I always thought these advantage card things were a bit BigBrother-y but I'm all for them now. If you've bought these teethers you should take them back for a refund - they are blueygreen transparent in the shape of a penguin and a whale (surprise surprise).
DS has given up on bespoke teethers, preferring my mobile, the remote control, my thumb knuckle, DD's Little Tikes slide, the legs of his laundry basket, the legs of his Sparkling Symphony, the kitchen table, well anything really apart from teethers, so this recall is all profit for me - woo hoo
