An Aussie one-year-old has grown so large for his age that he has to wear adult nappies.

Baby Sonny weighed over four kilos when mum Jayde Leeder gave birth last December.

And he has continued growing – now tipping the scales at a staggering 16kgs, The Sun reports.

The tot has consequently outgrown the largest size of Huggies nappies that the brand have to offer.

In a hilarious TikTok video, mum-of-three Jayde explains that she has had to go out and buy adult nappies for Sonny – because the baby size doesn’t fit around his waist.

When Jayde was pregnant with Sonny doctors were concerned she had gestational diabetes due to the size of her stomach and her extensive weight loss.

They checked four times for the condition, but, as it turned out, when Jayde finally gave birth, Sonny was just bigger than they’d expected.

Jayde, from Sydney, said: “When I was pregnant he always measured a week or two bigger.

“Doctors were concerned about his size and they originally thought I had diabetes but thankfully that wasn’t the case – I just had a special boy on the way.

“His dad is a big solid Russian and my oldest was over nine pounds when he was born so it was to be expected in a way.

“Sonny’s a happy little character and he makes some hilarious faces – he is very cheeky.

“He knows when he’s doing something he shouldn’t be and thinks it’s funny to see my reaction.

“He’s crawling and just learning to stand, but I have some skeletal problems and he seems to have inherited a few hypermobility issues as his ankle joints are a bit stiff.

“It’s nothing serious though and he is having regular physio so he will walk soon enough.

“I’m very lucky to have him in our beautiful family and can’t wait to watch him grow and develop in the future.”
