Pregnant Brain

I understand the physiological changes that happen to women during pregnancy. I know, for example, that the uterus expands from an organ that weighs 70g with a cavity space of about 1ml to an organ that weighs more than 1000g that can accumulate a fluid area of almost 20L. What I didn't realise is that the brain also has to make room for this little tyke!
At the best of times, the wife has always had the most entertaining brain. Believe me, she has come up with some pearlers in her time. However, with the addition of the zygote, her brain cells have all packed their bags and relocated to more suitable climates.

From one minute to the next, she completely forgets what it is she's talking about and subjects chop and change at will and God help you if you don't keep up. You could be discussing what to have for dinner and the next sentence has something to do with how viscous the mucus is.
"In the soup???"
"No, silly," eyes rolling like you're the most dense person to walk the face of the planet, "in my uterus! Keep up for heavens sake!"

Another new turn of events is the way she just makes up words for things because in the heat of the moment, she can't for the life of her remember the proper names. Let me give you an example...

Picture the scene: It's about 10pm and we're getting ready for bed. The wife has just been for her seventeenth visit to the WC and is now complaining about this.
"It's like this neverending circle of Fafa!"
"I'm sorry....circle of what??"
"Fafa!"
Cue dumbfounded look on my face.....
"Fafa!! You know, I lie in bed and get sleepy, then I need to pee, so I get up and pee, then I have to wait to get sleepy again, then just as I'm about to fall asleep, I need to pee again... a circle of Fafa."
"And what exactly does Fafa mean??"
"You know....Fafa!!. Just Fafa!"
And the eyes roll again like I'm the densest person around.

The descriptions also get "Krissified".
"How you feeling today, my love?" gets a response similar to "I'm twitchy....and pully". Not quite sure how to take that, but generally nodding and saying something like "I'm so sorry, baby...can I rub your tum?" is normally the right way to go.

Either way, if I don't keep up with the conversation or if I'm not sympathetic enough to the twitchy pullies, I'm generally in a world of Fafa!!
