Every day hundreds of people are trolled online, but there seems to be be a worrying increase in pregnancy-related body-shaming in recent weeks.

One of the latest women to speak out against this trend is Australian lawyer and fitness guru Daegan Coyne whose baby bump has been criticised online for being too small.

The mum-to-be took to Instagram this week to speak out against the trend while sharing a picture of herself (and her bump) in a multi-coloured bikini.

Sharing a similar message to that of American blogger Brittany Aäe, Daegan pointed out that no matter what size a pregnant woman is there always seems to be someone willing to tell her that her shape is unhealthy.

She wrote: “I have had pregnant friends called out for being ‘too big’, others ‘far too muscly’ and myself, the ‘you're way too small’.”

“Given I am yet to see one lady carry their pregnancy shape and size the same as another, I believe it's safe to assume peeps that there is no ‘one size fits all’ pregnancy.”

“I know heaps of the comments aren't meant to be hurtful or upsetting by any means, but we all have enough to worry about being a new mum (omg scary) let alone whether you are the size you are ‘expected’ to be.”

The bodybuilder went on to highlight that it is very difficult to accurately judge the health of a baby by looking its mother’s bump.

She said: “I don't think anyone even knows what this size is. I've been told one day I am carrying really high and the next ‘wow you are carrying so low’.”

“Bubba is in fact above average size for at 30 weeks, I am just good at hiding her.” 

Fair play to Daegan for standing up for herself and other expectant mothers.
