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:
