(This is Mr. Bee, just to clarify.)
It started in the bath tub... Charlie poked at my chest one day with his finger and giggling. I made a mistake and gave him a big reaction and told him "NO!", and he was hooked.
Even though I have never since given a big reaction, he has still likes to poke my nipples from time to time while he describes what he's doing out loud. It's decreased in frequency though, and so I thought maybe he had completely forgotten about it. But then today at the public pool, I was carrying Charlie around the pool and he started up again, saying, "I push the button, I push the button, I push daddy's nipple!" really loudly.
I think time stood still for about 10 seconds, as everyone in my vicinity looked at me and stared at my nipples. I just acted all nonchalant, especially because I didn't want him to be motivated by a reaction. But inside I was dying.
I hope he stops playing with my nipples soon... because I have a limited lifetime supply of embarrassment, and he used up like 20% of it today!
Does your LO ever do anything inappropriate in public? How do you manage it?
