This adorable but heated interaction between two three-year-old's discussed the big topics, whether wearing a diaper makes you a baby.

Roxann Warren, from Bolivar, Missouri, whipped her camera out when her grandson Daxter, and her adopted daughter Emerson, began the diaper debate as Emerson has been wearing the pull-ups due to a kidney issue.

Daxter was saying to her peer that wearing nappies confirmed whether or not the individual was a baby or not, but Emerson was adamant that she was not a baby.

Emerson began poking and prodding her relative demanding that she was not a baby to which Daxter simply kept reminding her that she was wearing a diaper and therefore had to be a baby.

The argument continued in this fashion until Roxann could not contain her laughter over the childish reasoning.

Roxann said: " My adopted daughter just got out of bed when my grandson showed up. He didn’t know she wore pull-ups to bed for a kidney issue and began questioning her as to why she was wearing a diaper.

"She just woke up was not ready for all his questions. By the time I got my camera out they were in a tizzy.

"I was pretty pleased she was able to control her temper as well as she did."
