When life hands you lemons… pull a funny face. That’s what these kids did, anyway.

When the kids won’t nap and they think your head is a bouncy castle, it might be time to sit them down for a snack. Something healthy, like fresh fruit…

Parents put their children forward for a cameo in a short movie called Pucker.

In the two-minute film, a handful of toddlers react to the taste of lemons for the first time - and there were some mixed reactions.

The clip starts with the tots studying the fruit before summoning up the courage to take their first bite.

Watch their little faces as they bite into the slices: some of the babies are disgusted by the sour taste - with one poor boy bawling his eyes out – while others actually seem to enjoy the taste, or at least put on a brave face.

Created by directors April Maciborka and David Wile, the video has already gone viral, racking up more than 130,000 views on YouTube alone.
