So yesterday I caught Lunchbox (the cat) in the baby's crib...And I yelled a lot. I understand that she's a cat and is therefore curious, but she also catches rats with her face. And given the choice, I'd rather not expose the baby to rat-germs. Maybe I'm just being a paranoid mom-to-be, but let's not forget who spread the bubonic plague through most of Europe.
Aaron suggested that we cover the top of the baby's crib with a screen-like device, thereby creating a baby-quarium.
And if you wanted to encourage your child to join the circus later in life, that might be the best start. But for now, the nursery door is closed, the baby is in utero, and the cats are still catching gross things on a regular basis.
