They say it's unwise to mess with a pregnant woman, but it seems some people still don't know when to keep their thoughts to themselves.
Women subjected to rude comments while they were expecting have taken to the parenting forum Mumsnet to share the most inappropriate examples - from their bump being described as 'huge', to warnings that natural childbirth was a one-way ticket to a divorce.
One user recalled her boss advising her: "Make sure you don't have a vaginal birth or your husband will leave you - and with good reason!"
Another user said that her mother-in-law was not impressed by the quality of her scan and pulled out the her sister-in-law's scan for comparison - pointing out how "wonderful" it was, reports Daily Mail.
The debate kicked off when one mum told fellow users how shocked she was by the type of snide remarks that friends and even family members made during her pregnancy.
