Which side do you hold your baby on?
I had to think about that for a moment but it's definitely the left hand side in my case, although that's mainly so that I have my right hand free for holding a cup of tea or scoffing a biscuit.
But according to new research, it could have a much more scientific explanation than that.
New Scientist reports:
'Mothers hold their children more on the left and wild mammals seem to keep their young more on that so too, at least when fleeing predators. Now it seems many mammal babies prefer to approach their mother from one side too – and the explanation may lie in the contrasting talents of each half of the brain.'
Could it be that we perch our babies on our left hand side so that we can read their social cues and facial expressions better?
I love that idea, and any notion which hints at the clever stuff that's going on beneath the surface of what seems like routine mother/baby interactions.
I still reckon the ability to hold a cup of tea steady whilst caring for your child also has evolutionary value, though!
What's your view? Do you hold your child on one particular side? And do you think it has a clever scientific explanation or are you all about the biscuits too? Leave us a comment below or come and join the conversation over on our Facebook page.
