We're sure you've felt those eyes of your toddler on you and felt like maybe they were judging you a little.
Perhaps you brushed it off as your sleep-deprived imagination but guess what?
You could be right.
According to a recent study by the American Psychological Association, kids by the age of five can make character judgments - based on a person's facial features that same way adults can.
Researchers carried out four different experiments with around 350 kids between the ages of 3 and 13.
Adults were involved in some of the experiments as a control group so the researchers could use them to compare.
So could the kids could predict the behaviour associated with a certain face?
They were shown pairs of computer-generated faces that were created to show trustworthy vs. untrustworthy, dominant vs. submissive and competent vs. incompetent.
They were asked which people seemed ''nice'' or ''mean'' or which person could "pick up heavy things".
Then the second version of this experiment saw researchers making the features more subtle to see the effects.
So, it was found that kids who were three-years-old and the adults made the stereotypically expected judgments 88 percent of the time.
Tessa E.S. Charlesworth, the lead author of the study, ''"This shows that children from as early as kindergarten use facial appearance to determine meaningful judgments and expectations of others' behaviour.''
Who knew our toddlers were so in tune with adult bevaiours?
