Mila Kunis this week claimed the behaviour of her son and daughter proved that women are smarter than men.
But I have to question whether the behaviours of Kunis' daughter 3-year-old Wyatt Isabelle and 1-year-old Dimitri Portwood should actually be attributed to gender.
After reading her comments, I realised the difference she describes between the behaviour of her first and second children also rang true for my first two kids - and I have all boys.
Appearing on The Ellen DeGeneres Show, the actress said, "They're incredibly different. My boy's like a sloth. He's wonderful and I love him, because one day he'll probably watch this and be like, 'Why would you say that?' But the truth is, women are smarter than men, and I have this evidence from my two different humans that I created. Girls are just like on it and boys are like, dum dun dum.
"They're just like a little bit more like little linebackers going through life, and like Neanderthal-ish. So there's an element where Wyatt will be like, 'Pass the cup please.' My boy's like, 'Eh, eh.' That's it! That's all you get. And you're like, 'Eh? What could eh mean?'" she said. "There's just a huge difference."
Kunis admits her son is only 16 months old, before pointing that her daughter was radically different at the same age.
But couldn't these differences be less about gender and be attributed instead to the siblings' birth order, or something else entirely? With the undivided attention of many adults, my eldest son was also a self-aware and articulate communicator from a very early age. My second son, not so much. He was much more the "Eh, eh," kind of kid for the first two-and-a-half years of his life.
Even now my first son shows all the classic signs of being the eldest - much like little Wyatt. He takes on more responsibility, is more aware of the things that need to be done, adjusts his behaviour more according to the social situation he's in and relates to adults more.
The second child is much more, well, childish. And I mean that in the nicest possible way. He prefers to stay ensconced in childhood, unlike his older brother who always wants to leap several stairs at a time to adulthood instead of taking them one-by-one.
With all that said, there are those who believe birth order is as much of a myth as gender affecting personality.
Mila, as much as I love you, I'm going to call this one out and say it's probably got a lot more to do with personality, developmental age and perhaps birth order, than proof of any great revelation about the sexes.
