Nowadays, Zen knows that he has to brush his teeth before going to bed. He always (and I mean always) make a fuss about it but we were determined not to give in and insist that he brushes them. However, he tried using toothpaste a few times but he didn't like it so we let it be and will try again off and on.
Anyway, when Zen was brushing his teeth just now, he pressed some liquid hand soap onto his toothbrush and brushed his teeth with it! Dunn why he did that though... But he went "ARGHHHH!!" and hubby made him rinse his mouth many many times.
One thing for sure, his mouth is clean :-)
