United in grief, three mothers stand with their arms entwined as their beautiful children, with their beautiful smiles, are remembered in the most fitting way possible.

The peaceful area of Heath Park stands just a stone's throw from Wales' largest hospital but the painful memories of that place are hidden from view by the oak trees that flutter in the breeze.

This is a "happy place" where the mums came with their children to escape the difficult treatments they had to endure as they battled for life.

It is here the grieving mothers and their families still come to remember and cherish their loved ones and, thanks to charity Dreams & Wishes , they now have a focus for their memories and the memories of others who have lost children.

Three memorial benches have been placed in a quiet corner of the park near the University Hospital of Wales in Cardiff and 'celebration of life' oak trees have been planted around a stone monument to children who have lost their lives.

One of the benches is etched with the words 'An infectious smile to cherish forever'.

It is just one of the sentiments behind a group, called Beautiful Smiles, that was started by mums Sarah Fussell, Bec Pugh, and Sarah Griffiths with the help of the charity that supports seriously ill children and their families.

All three mums lost their daughters when they were too young and have bonded over their loss and the need to be able to help others going through what they have gone through.

They wanted a group where they could talk with others who knew exactly what they were going through to help them and others realise the emotions they were feeling were not strange and to provide a support that was not available in the area at the time.

The name, fittingly, comes from their daughters' beaming smiles that lit up even the darkest of times.

The commemoration area was officially unveiled by Secretary of State for Wales Alun Cairns and Tony Curtis from Dreams & Wishes on May 2.

Mum Sarah said after her daughter's death there was nowhere for bereaved parents to be able to share their grief.

"You can have counselling but Beautiful Smiles is not about counsellin. It is about getting together with other parents who understand exactly what you are going through," said the mum-of-three from Allt-yr-yn, Newport .

"They understand the experiences you are going through. You can say things there that you wouldn't say to anybody else.

"It is important because we are all with other every step of the way."

Sarah was joined at the launch of the memorial by husband Jason and daughters Charlotte, 12, and Eve, 20.

"It is beautiful to have this place to come to," said Sarah. "We would come here with Libby to get away from the hospital for a bit and we have such lovely memories of our time in the park.

"I can't go over to the hospital myself, it is too painful, so it is wonderful to have somewhere to visit."

Sarah Griffiths' daughter Daisy was only 14 when she died two years ago after being diagnosed with Ewing's Sarcoma, a rare form of bone cancer.

Throughout her ordeal Oakdale Comprehensive pupil Daisy never stopped smiling.

Since her daughter's death Sarah has put her efforts into fundraising to put a smile on the faces of other children with serious illnesses.

She has raised more than £30,000 and is delighted to see a special area where their children can be remembered and has spoken about the importance of the support group.

"It for anyone who has lost their angels," she said. "It is a place were we can talk about our children and keep their memories alive.

"It is about cherishing their memories and knowing that what you are feeling is normal because other people who understand and are going through it themselves.

"And now we have this beautiful area where we all have lovely memories when our children were receiving treatment. We can come here and just cherish everything that we went through knowing that the benches are in memory of our children.

"It is so peaceful and a happy place rather than sad. A beautiful place of peace and happiness and fortunately you can't see the hospital from here.

"It was a very emotional time coming back on the route we used to come to the hospital, but this is a positive area."

Mr Curtis MBE, from Dreams & Wishes, said: "Something that came up when we started Beautiful Smiles was that is was important for us to help create a beautiful area for the families. We knew a lot of families come here because it is near the hospital and every time we come here the sun seems to come out.

"We know how difficult it is for these parents, what they go through every single day, and we try to create special memories. I look back and see all the smiles, and all the laughter, and this is a special place where families can remember that."

Bec Pugh's daughter Martha died when she was just 13. She believes even though their children are not physically with them they live on at the memorial.

Bec, from Cardiff, said: "Our children were so brave and courageous and strong and the oak trees that have been planted here reflect that. Even though we don't have our children here with us physically they live on in this place."
