Well ours are anyway! I keep meaning to do something (like soak them in milton) but obviously not high up on my list of priorities (or I'd go and do it now), I just wince when one of the DCs squeezes another mangey duck and all that black sh*te floats round the bath - bleeurrghh.
Is this the bit where I am outed as a complete scrubber and everyone else sterilises their bath toys weekly?
