On July 27, Kirsty Burnett will release white balloons into the sky in silent tribute to the baby boy she lost, suddenly, weeks before she was due to give birth.

Kirsty's son, Marcus Alexander, died in the womb when she was eight and a half months pregnant without warning.

She suffered a placental abruption, where the placenta comes away from the womb, starving the baby of oxygen and nutrients.

She clutches a treasured photograph of her son taken in the hours after he was delivered weighing 4lb 7oz, that now hangs in the living room of her home in Pollok in Glasgow's south side.

"It helps because even though I won't get to see him grow up, you've still go those memories," says the softly spoken 21-year-old.

"When I was pregnant, I didn’t think that things could go wrong.

"I thought there was a very low percentage.

"I am in that low percentage today."

Kirsty was eagerly anticipating the birth of her first child and had suffered no complications during her pregnancy with plenty of movement.

She says: "Through the night he would sleep, then at 5 or 6 in the morning he would wake up.

"On July 20, I wasn't feeling well. I was being sick. I just thought I had a bug but it just kept on happening.

"Eventually I went up to the hospital and they said that his heart had stopped.

"I just went numb. I couldn't feel anything.

"His placenta just broke away and he instantly died. They said that even if I'd gone up to the hospital earlier that night, they wouldn't have been able to identify it and he would have still died.

"Usually they send you home but they kept me in because I was still being sick.

"They gave me tablets to start the labour.

"My mum was with me. We got two days with him. I didn't know what was going to happen. I gave birth and they brought in a cool box to keep his body cold.

"I helped bath him and they kept him beside me. They got him dressed and I could give him cuddles.

"At first I was scared to hold him because it was different. Then I was scared to bath him because I thought they were going to take him away, straight away but it didn't happen.

"Then he was taken away for the post mortem. At the funeral home we got to spend two days with him.

"It's hard but you just need to get on with it. I have my good days and bad days."

Kirsty's mum Karina, 52, has Marcus's name tattooed on her wrist and says it was "heartbreaking" to watch her daughter suffer the heartwrenching grief of stillbirth.

She is taking Kirsty away for a break to Craig Tara caravan park in Ayr for this year's anniversary, where they will release the balloons.

She said: "It was heartbreaking for her and it was heartbreaking to watch her go through it. I've never gone through anything like that. I had four healthy children.

"Marcus was moving about a lot. That was what was so shocking about it.

"I couldn't stop crying. I've

"I'm here for her whenever she needs me.

In most cases of placental abruption, the placenta comes away at the edge, and may cause just a small amount of bleeding.

The condition can cause premature birth, growth problems and in the worst cases, stillbirth.

It's not clear what causes placental abruption, but factors that increase the risk include injury to the abdominal area, smoking and high blood pressure.

Kirsty says she wants a family at some point in the future and is keen to return to her training to be a nursery teacher. Any future pregnancies will be monitored more closely.

On August 27, Kirsty and around 200 mothers, relatives and friends will take part in a 10k walk from Glasgow Green, dressed as Disney characters, to raise funds for the charity SANDS - Stillbirth and Neonatal Death.

She says; "I do want more kids but I don't know when. The doctors told me it won't happen again and that they would look after me and give me more scans then at 36 weeks they would take me in and start my labour.

"I don't want another mum going through a pregnancy thinking this will be fine and then something goes wrong. I don’t want another heartbroken mother.

"All things can happen. It can happen for no reason at all and you don't get an answer.

"I want to make sure that expectant mothers are more cautious of risks during pregnancy."
