Three-year-old Jay is a big brother. But don’t call him that. He prefers grandpa.

The adorable toddler has told his mum, Julie Wise, over and over that he doesn’t feel like a kid, he feels like a grandpa. So she’s helped him embrace his individuality, buying him a wig and glasses – even a toy pipe.

She’s shared several videos on her TikTok account, even answering what happens when they go out in public.

Julie explains that when she took her baby to the doctor, Jay told the paediatrician that he’s not a big brother, he’s a grandpa.

“Of course, he said, ‘I’m actually a grandpa.’ And the doctor looked at me and was like, ‘A grandpa.’ I was like, ‘Yes, he wants to be her grandpa. We call him Grandpa.’”

Julie says while Jay is free to express himself as a grandpa, “We don’t bring the wig out in public, though. We do have boundaries here.”

There has been some backlash on the videos, with one person commenting, “This is so f****ing weird. Parents are spineless these days. You aren’t a grandpa because you’re a child, why do people lie to their kids?”

To which Julie replied, “I feel bad for people who take life so seriously.”
