An 'emotional terrorist' has blamed a mum with terminal cancer for the death of her baby in a cruel comment left on her blog.
She was diagnosed with inflammatory breast cancer and given between two and five years to live when she fell pregnant with daughter Ally.
The mum made the decision to delay treatment for herself to give Ally the best chance of survival.
But, tragically, when Ally was born 12 weeks early in December 2015 - she contracted an infection, and died just days later.
Heidi says most of the posts made about her are supportive, but one post stood out as particularly cruel. The user, typing under the name Kitty Meijer, said, "Cancer had nothing to do with her [daughter's] death".
The cruel post reads, "But no, you just chose to continue breastfeeding and planning your pregnancy (they must have really loved you at work, three in three years, way to put more work on your co-workers) and generally only thinking of how awesome you were as a person.
"Then, when you already had two kids you decided that they and your husband were less important than it was for you to be a martyr, so you decided to f**k it all and delay cancer treatment so you could have another baby."
Meijer adds: "Cancer had nothing to do with her death, your GODAWFUL CHOICES however, led directly to her death.
"Thank God Ally got taken away from you, you selfish lying miserable excuse for a mother and a human being.
"Your choices concern only you, and everybody around you just has to deal with your s***. You made your cancer bed, now lie in it and die."
Speaking to the Bristol Post, Heidi said she believed it was important to expose the troll to help other women who might be targeted.
"I know someone writing under that name has targeted another mum who has also lost a child," Heidi said.
I have such a lovely group of supporters, there was no way this person was going to bring me down. But I did want to share their comments to help other women who might be targeted.
After the story made headlines Kitty Meijer posted another commented on Heidi's blog again, saying, "you killed Ally and derived your boy of their mum".
Sharing a screengrab of the comment in a Facebook post, Heidi, who is mother to Noah, 4, and Tait, 3, said, "This person has no chance. What I’ve been through, if that hasn’t broken me, why on earth would this?"
