Please don't wipe your brother's bare bum and then stick the wipe in your mouth!!

Please don't touch your brother's penis. That's his.

I know his balls are floating in the bath, but please don't touch them.

Please don't feed your brother muesli bar (at 4 days old).

Please don't stick your toe in your brother's eye. It makes him sad.

Please don't lick your toe.
