FROM radiant complexion to the more obvious bump, there are many changes in your appearance when pregnant.
But one mum claimed others could never tell she was carrying baby number two in her belly and they were stunned when she turned around.
Brittany Christiana, who first became somewhat of an internet sensation after sharing adorable videos of her daughter, Lily, took to Instagram to reveal just how receiving her pregnancy bump was.
The US-based mum, whose account, , has amassed close to 2million followers, posted a video - and it's safe to say, we're just as shocked as everyone else.
In , Brittany was posing with a stunning red velvet dress with her belly facing the wall.
Then, with music in the background, she turned around and revealed her massive baby bump that was home for Violet, Lily's sister.

In fact, the belly was so big, the mum-of-two claimed she had to be sleeping in a chair, as bed was no longer an option at the time.
After sharing the video on social media two weeks ago, Brittany was rushed to the hospital where she delivered Violet ''smoothly'' at the start of January.
''I seriously never thought a C-section could be so peaceful and beautiful at the same time.
''We are beyond grateful, happy and blessed! Mama and baby are doing so well- so is dada!'' the family-of-four wrote on their Instagram page.

But perhaps what made our hearts melt the most was Lily's reaction when meeting her new sister, which the toddler described as ''tiny''.
''I love her,'' the big sibling exclaimed whilst holding the baby girl.

''I love her feet - they're so little.''
Sharing the adorable video, the mum said it was her ''favourite moment in history'', and social media users flocked to comments to congratulate the parents.
One fan wrote: ''Baby violet you have the most loving sister.''
Another penned: ''There is just something way too sweet about a big sister’s love for her baby sibling!''
''Aw this is so adorable!!! Congratulations all,'' a third added.
''Oh I’ve been waiting impatiently for this,'' said someone else who had been following the journey.
Last year, Brittany was slammed after revealing the way she got Lily to come off her dummies - will she try the same method on Violet?
The TikTok-famous mum came with a quick and easy solution - to simply break one of her daughter's favourite binkies.
''One a week until she is binky free!''
In the video, which has since seen seven million likes, she could be seen cutting the dummy into two and handing it to her toddler, Lily.
''I'm so sorry, Lily.''
After a careful inspection, the daughter asked if it's broken and added: ''Dada will fix it.''
Although the method is quick and has helped Brittany to reduce the total of binkies from four to two, there were viewers who slammed her for being cruel.
''Just mean,'' wrote one critical person on Instagram.
''This approach would of caused a total meltdown for me as a child,'' another added.
''I would of been inconsolable.''
Someone else thought that ''the laughter hides the pain''.
Other parents shared their tips and tricks, like this one who wrote: ''I just avoided this by not giving them one in the first place.''
One mum commented: ''I told my daughter that she is going to kindergarten soon and they don't use them anymore and we have to throw them away.
''I gave he one and open the trash bin and she threw them away herself and after that she never used one again even if you asked if she wanted one.''

''So my mum used a trade off of “give your dummies to the tooth fairy and she’ll leave you a little companion,'' shared one person.
''Worked wonders for me, still have the little teddy bear, he’s mostly ornamental these day.''
