Growing so big so fast

So a couple weeks ago Lil' Genghis celebrated her 4th birthday, in Brasil, with Norwegians. It confused dad, who wasn't there, but clearly didn't confuse her.

"I'm not three any more!" she said into the phone. Such a mature way of phrasing things, no?

Or so dad thought. Yesterday, mom left an electronic message for her husband. It seems mom and Lil' Genghis got talking about Cassie, a stuffed unicorn Lil' Genghis considers her daughter.

Mom, I am not married to Cassie's dad anymore. We separated.

Really, Bebel? I'm sorry to hear that.

Yes, but we still sleep together.

What the heck happened to the little toddler we had?
