A photo of a five-year-old girl next to a cardboard cutout of her grandma was put on display at the National Portrait Gallery.

In the photo, taken by Teddington resident Melanie Lowis, 37, her daughter Millie is doing her homework next to a hand-drawn cutout of her grandmother.

Never without her Grandma was one of 100 portraits to be displayed out of 31,000 entries to an exhibition launched by the Duchess of Cambridge.

Millie, five, is extremely close to her grandma and missed her a lot during lockdown.

Brenda Dunn, 73, depicted in the cardboard cutout, was overcome with emotion when she first saw the photo.

Brenda said: "The picture honestly made me cry when I first saw it."

Brenda, a widow, moved to London a little over five years ago to be closer to her family.

She spent nearly every day with Millie after Melanie returned to work after maternity leave, giving the two with an unbreakable bond.

Melanie, now a stay-at-home mother, said: "Mum was obviously in lockdown on her own and she's not very good at using technology. She wasn't really able to use Zoom like everyone else was.

"Millie came up with the idea when we were trying to get her to do schooling stuff. She said: 'The only way I'll do [my homework] is if Grandma does it with me'."

Millie got creative and her cardboard-cutout-granny was born.

Melanie said: "She used to take it around, lie on the sofa with it, watch a bit of TV with it, you know, carry it around the house a bit."

Brenda, having spent most of the lockdown in isolation, found the whole exhibition extremely moving.

Brenda said: "I looked at them all and I was stunned. It's such a wonderful project. I'm almost crying now thinking about them."

The pair have since been reunited.

Millie, her mother, her 43-year-old father Mike, and three-year-old brother Harry, were able to become part of Dunn's support bubble at the beginning of July in line with restrictions.

Melanie said of the reunion: "When we said [to Millie], okay you can hug [Grandma], she just sort of hugged her legs and didn't let go. It was so sweet."

With Millie restarting school in September, their reunion was short-lived, as Brenda could not afford to subject herself to the risk of a potential coronavirus exposure from Millie's school.

The pair hope that this second period of separation will be brief.

Hold Still is a digital exhibition, launched by the Duchess of Cambridge, and aims to capture life in Britain during the coronavirus pandemic.

A selection of the photographs will be displayed in towns and cities across the UK later this year.

The cardboard cutout itself is not in the National Portrait Gallery, but in Dunn's house, hanging in pride of place on her wall.
