New parents can spend many a happy hour gazing at their baby's beautiful features - but if we're honest part of the fascination comes from the hilarious array of expressions that can cross a baby's face.
We're especially fond of occasions when a baby pulls a face that makes her look far older - and wiser - than her actual age.
And it appears we aren't the only ones who love it when babies bear more than a passing resemblance to their grandparents. Parents have now taken to sharing their favourite photos capturing these very moments on reddit.
Scroll down to see some of the funniest posts on the feed so far:

A dip dye you say? In my a day we'd have called that an argument with your hairdresser!
Old? Me? No I'm just a method actor ... you did say you wanted me to be a 'grizzly' bear!
Not yet a month old and this baby's already world weary.
80 days or 80 years old?
What is that newfangled gadget you keep pointing at me?
15 minutes old and already tired of your nonsense
Malcolm Rifkind, is that you?
Proof that even babies born with a full head of hair can't escape the old man comparisons.
