... and on the topic of baths.
It only took me months of sitting next to the bath (and years of my life as someone who has used a bath!) to work out how to sink bath toys completely.
I'm not sure how it took me so long to work out how to tilt the airhole to the top and to squeeze the toy underwater until no more air bubbles come out (thus anything going back in will be water), but I did it.
And I felt like a champ!
