Bella's definitely reaching that stage where we need to be ever more vigilant about what we say around her.
When she woke up yesterday, she said "I had a bloody fly in my bedroom last night - mummy was chasing it around." Later on, while sitting on the loo she said "My poo is coming from Pooland on a choo-choo train through my bum-tunnel." A metaphor I fear was pieced together from several things I'd said earlier.
Probably shouldn't have F'ed and C'ed and T'ed in the car this morning then, at the idiot who decided he was more important than all the people at the junction waiting to turn right and overtook them all to turn left.
