She purposely posts photos showing her differences, to prove no one is perfect – not even social media influencers.
"I've said this before – I LOVE my body so much and am grateful for everything it has done for me & my kids!" she continued in her post.
"I made a promise to myself the day I gave birth to my son Izaac (on my lounge room floor btw) that if I were to ever have negative thoughts about my body I'd remind myself of what it's done for me and how blessed I am. I haven't yet had to remind myself though."
Emily said that even though it "doesn't matter" what others think and say, it "still does affect a lot of us".
"Nasty comments like the above do upset me initially but then I take deep breaths and let it go," she told her followers.
"I know these people are being far from constructive and their only goal is to hurt me. I always try to turn a negative into positive though and I'm using them as motivation.
"So thank you nasty people, instead of bringing me down you've only made me stronger, more determined and more resilient."
Emily said it makes her "sad" when she hears people say terrible things about the way they look.
"Love for yourself and your body isn't easy and takes time to learn how to do it but I believe it's SO important," she said.
"The best way to love your body I think is to appreciate what it DOES for you – focus on that and nourish it with nutritious food, exercise and rest."
Emily explained that while she loves feeling strong with an aim to improve her fitness, it doesn't mean she's isn't in awe of her body when it's not at its "peak".
"I truly loved my body throughout my pregnancies, right after giving birth and I love it just as it is right now and will continue to love it for the rest of my life," she added.
"I have even more reason to since becoming a mother and I want to be a good example for them."
Emily, who's eldest daughter Mia is now 2, said she "will be fit and strong again".
"Because I want to and I'm doing it for myself on my OWN terms. I'm feeling better, stronger and fitter every single day."
Since sharing her post on Tuesday night, it has been inundated with almost 4000 comments and over 73,000 "likes" from fans applauding her for being open, honest and inspiring.
"This is a great message! You glow from the inside out and look absolutely beautiful!!" one follower wrote.
"You look fab and your dedication to regain your fitness is inspiring I just wish I had half of it (ps, that's what I think all the negative people feel)," another commented, adding laughing emojis.
"You look amazing!! Your body created two miracles and you are 100 per cent inspiration to mamas who may be doubting themselves. Thank you for always being positive!!" wrote a third fan.
