A heartbroken mother has penned an emotional blog post after no one turned up to her son's ninth birthday party.

The mother-of-six, who goes by the pen name Kristen Layne, shared the post on her website, Life on Peanut Layne, describing her son Mahlon as 'bright, sensitive and caring'.

She added that the young boy is also 'naturally funny, easy to please and looks at life with hope and optimism... the kid who would give the shirt off of his back to a stranger, hand over a beloved toy to make another child smile.'

But despite this, not one single child from school or Mahlon's taekwondo class came to his birthday party.

Excited: The mother-of-six shared the post on her blog, Life on Peanut Layne, describing her son as 'bright, sensitive and caring'

After Mahlon spent his first year attending a public school, after being home schooled for much of his life, Ms Layne, from Oregon, was sure that plenty of other children would turn up to his party.

'This ninth birthday was supposed to be his year. His special day. His first real party with friends,' Ms Layne wrote.

The doting mother chose a 'Diary of a Wimpy Kid' theme because it is Mahlon's favorite book series, and ordered him custom invitations on Etsy, an edible cake topper, and even planned some fun Diary of a Wimpy Kid-themed games.

'He handed out multiple invitations to his friends at school, and one [friend] from taekwondo, and eagerly counted down the days, hours, and minutes until his birthday,' she wrote.

'When his birthday finally arrived yesterday, he was up before the sun. He hung streamers, blew up balloons, cleaned his room, took a bath, picked out his outfit, set the table, and carefully assembled the treat bags for his friends.

'"Only three more hours until my friends arrive," he yelled. "This is the happiest day of my life, Momma. I can't wait until my friends get here!"'

Ms Layne shared pictures of her son posing by the party decorations all smiles as he waited for his friends to arrive.

'Excited and anxious': Ms Layne considered canceling the party but her son had assured her that five of his friends were definitely coming

Photos also showed the planned games, lolly bags and place settings for everyone.

But when the party start time came and passed, Ms Layne started to worry.

No one came Dad. I guess I'm not very popular at school

'I had asked parents to RSVP on the invitation, but hadn't received a single reply.

'Since we're new in town (and school just started a little over a month ago here), I didn't have phone numbers for any of the parents,' she wrote.

Ms Layne watched as her little boy ran up and down the street anxiously waiting for his party guests.

'But no one came. Not a single child,' Ms Layne added.

She explained that, despite having ordered enough pizza to 'feed a small army', planned plenty of party games and ordered a large cake, only Mahlon's family members turned up to celebrate with him.

'No one came Dad. I guess I'm not very popular at school,' Ms Layne described her son as saying, adding that he later started sobbing when he realized nobody was going to turn up.

Making the most of it: Mahlon's family took him bowling that afternoon

'Words cannot describe the utter and complete devastation that washed over me... seeing my heartbroken little boy sitting all alone at his brightly decorated, empty party table was more than I could take,' Ms Layne said.

Although Mahlon was joined by his family members, and a few family friends, who all enjoyed the cake and pizza together, Ms Layne admitted that she and her husband were devastated by the fact that none of Mahlon's school friends turned up - even though the little boy ended the day with a smile on his face.

Ms Layne added that she is 'too devastated to be angry' at the parents of the children who were invited; but while she doesn't blame the kids for not turning up, she urged parents to make sure that they RSVP to all birthday party invites in future.

Kindness of strangers: Since posting about the experience, little Mahlon has been sent a flood of gifts and words of support

'M will likely never forget his ninth birthday. It will forever be etched in his memory bank as that one year when no one came to his party,' she said.

It could've all been avoided by a simple RSVP, via phone call, text, email, whatever

'And that kills me as a parent. And it could've all been avoided by a simple RSVP, via phone call, text, email, whatever, etc.

'I know I will definitely never ignore those four little letters ever again.'

There is a silver lining to Mahlon's disappointing birthday experience however; since his mother shared her story online, the young boy has been sent a flood of gifts and words of support from people around the world who were heartbroken to ready about his birthday story.

'Our family wanted to send a huge, enormous thank you to each and every one of you for all the kind words, support, birthday wishes, cards, gifts,' Ms Layne wrote.
