Just a word of advice to parents with curious toddlers - either avoid this new product or make sure the toilet can be locked when not in use because i just caught my 18 month old eating one of the gel discs that she peeled away from the bowl. She consumed half of it and i'm kicking myself for having bought it in the first place because these gel discs look just like jelly lollies. We were told by the Poisons Information Centre that this product needs to be flushed from her system so i'm trying to encourage her to drink though she is not interested. And we were told just to keep a close eye on her tonight. This has been a huge wake-up call for us and i just had to warn others.
