Sandy Diaper Terror Level

We have just upgraded the Sandy Diaper Terror Level from orange to red. We are currently three (four?) days post beach trip and the amount of sand coming out the other end just appears to be increasing. More research is required to prove my theory (i.e. feeding Matilda more sand), but I believe sand quantity and diaper stink are positively correlated variables. While the diaper situation has been fine up to now, I am officially starting the count down to potty training - bring on the temporary tattoos.
