A savvy dad from Dorset in southwest England set up his Google Nest Hub Max next to the cookie jar to find out who was stealing biscuits.
The clip, captured on June 23, shows Henry sneak into the kitchen and clamber up to the biscuit barrel to sneakily grab a biscuit after bedtime.
"Great thing about having a Google Nest Hub Max is being alerted to your child going to the Biscuit Barrel when they should be in bed asleep!" Henry's dad, David, told Newsflare.
Luckily David saw the funny side in it and Henry was allowed to eat the two biscuits he had taken and hidden under his pillow.
