Thousands of mums are celebrating their #postbabybodies on Instagram with stunning pics

If you're a mum you'll know that getting used to your changed shape post-pregnancy can be challenging.

Over on Instagram there are thousands of women who are celebrating their new tummies by uploading before and after images of themselves.

Using the hashtag #postbabybody mums everywhere are showing that all women's shapes and sizes should be celebrated post-motherhood. And the subject obviously resonates with a lot of women. The hashtag has nearly 9000 uploads of amazing 'mum bods' on Instagram alone.

Of course, a lot of the examples are women who are proud of the weight they've shifted since having their little one. One user fit.mamms posted her picture alongside the caption, 'I'm still amazed at what the female body is capable of. Left I was 38 weeks pregnant and right I was 4 months post-partum.

'I'm not in anyway posting this to pressure new mums to get back into shape. I'm sharing with you my personal results from maintaining a healthy, active pregnancy and post-partum recovery.'

While fellow new mum Bronwyn Helgeson said '#missmybump but #lovemybaby' on a picture of her before and after having had her baby.

Some users of the hashtag, however, haven't had an entirely positive response to their images. One stay-at-home mum Nikki revealed that after her picture was published in an article about the hashtag she received negative comments about her body on Twitter.

In a post responding to the trolls she wrote, 'It took a lot of courage for me to post my progress pictures on Instagram.

'I feel so down about the nasty comments on Twitter from the Daily Mail Article that included one of my pictures (that I knew nothing about).

'I never posted my body shots for attention but to inspire others

'My girls are my world - my days are devoted to them. I'm getting fitter and healthier for them.

'Trying not to feel down, but it's hard.'

We think you look great Nikki, as do all the other mums!
