My sister was found dead with her one-year-old son – she was a lovely mum and lived for Harry

Speaking to The Sun he said: “She lived for her Harry. It is just one of those tragic things.

“The family is getting by, with the help of the close community.

“Natalie was lively and bubbly. She was such a good mam, a lovely mam to her son Harry.”

Devastated pals have described young mum Natalie as "lovely" and little Harry as "beautiful".

Friends of the young mum have been left heartbroken by the news, saying that they will "cherish" the memories.

Pal Ashton Graham said: “I just want to say what a brilliant mam she was and how proud we all are of her.

“She’s touched a lot of hearts and she’ll never know how truly loved and special she and baby Harry are.

“When people say your best friend can be your soulmate, I truly truly believe that’s what you are.

“A part of me has died with you, my life will never ever be the same without you, nothing will be the same again.

“He was such a happy baby. You were such a brilliant little mam, protected him from any harm, made sure he had everything he needed.

"You gave him the best life, he was the making of you.”

The fundraiser in their memory has raised more than £4,000 so far for the funerals and Women Out West, a charity that previously helped the mum.

'DOTING MUM'

A statement on the GoFundMe page said: "After the tragic news and sudden loss it's only in our best wishes to give Natalie and Harry the best send off possible.

"We would like to give Natalie's family a big help by contributing to this as this is what they deserve.

"We're not asking for the full amount but every little helps and if were to receive more than expected Natalie's brother Shane's chosen charity is Women Out West.

"This Charity helped Natalie out so much and Shane is so pleased that they were there for Natalie that this is the best way to say thank you."

Friends and family of Harry have urged peopel to change their profile pictures to Hey Dugee in memory of the little boy.

They have also organised a memorial for the mum and son - with organisers asking well wishers to bring blue, pink and purple balloons to Castle Park.

One neighbour described her as a "doting" mum who loved her "beautiful" little boy.

They added: "She was a lovely lass and absolutely doted on that little boy, he was beautiful and this is such a tragedy.

"The police haven't told us what happened, just that Natalie and Harry were found dead in her flat.

"There was nothing alarming beforehand, the only unusual thing was that there seemed to be water constantly running down the waste pipe.

"It sounded as though a bath or sink had perhaps been overflowing.

"The police were asking neighbours if they had seen Natalie and the next thing I knew there were police officers and paramedics running into the flat.

"When they told us they'd both died it was heartbreaking".

Cumbria Police have confirmed that they are not treating the deaths as suspicious.

In a statement they said: "Police attended an address in Wellington Row, Whitehaven, after being made aware at 2.52pm on December 30 of a concern for the welfare of a woman.

"Sadly, two people were found deceased in the address - a woman in her twenties and a one-year-old child.

"There are no suspicious circumstances at this time. The coroner has been contacted."
