And by that I mean real pure obsessions.
My 3 year-old DS has been nurturing a passionate love for toilets/hand-dryer for about 18 months (the cute "phase" turns out to be rather tiring). Wherever we go (playgroups, playgrounds, swimming pool, zoo, restaurant...), he first locates the toilets and then will do everything in his power to trick us to go here. A year ago, I was thinking potty training would be a ball. Well no!
Anyone with this kind of thing?
