How would I explain that??

The other day the topic of poop came up in our conversation. Maybe I was telling Izak about Stacey's blog, I don't know. But for some reason Izak kept saying the word 'poop.' And Bea, who's trying hard to say new words, was mouthing, 'pah, pah, pah.' I realized what she was doing and I quickly told Izak to stop saying 'poop.' I don't want 'poop' to Bea's first 'real' word. Then I did it again! I was changing Bea and I gave her some of her 'butt balm' to play with. Well I kept saying butt balm, and before I knew it she was saying, 'bu, bu, bu.' I was thinking craaaap! Now she's gonna say butt! I guess we're gong to REALLY have to watch what we say.
