It's not the long coats or the way Kate Middleton carries her clutches that keep her baby bump hidden, it turns out the Duchess of Cambridge's barely there belly runs in the family.

Kate, who is set to give birth mid-July, is having a very similar pregnancy to her mother's, according to Hollywood Life.

"Carole didn’t show for a long time,” sources told US Weekly.

Mrs. Middleton, who gave birth to Kate, Pippa and James, also kept a smaller frame.

“She wore non-maternity clothes right up until the final weeks. So it was no surprise to the family when Kate stayed little,” sources tell the magazine.

While the size of the Duchess's frame has caused some speculation, it doesn't seem to worry the Royal couple. Instead, sources say, Prince William and his wife are closer than ever.

Mark Stewart, a royal photographer, tells People magazine the couple have been much more "touchy-feely."

As of now, the couple haven't decided on a baby name, but they seem to have narrowed it down to Philip for a boy, and Elizabeth or Diana as a middle name if they have a girl.

  • Alexandra

    <strong>FAMILY TREE</strong>: Queen Elizabeth II (a.k.a. Elizabeth Alexandra Mary), Queen of the United Kingdom and the Commonwealth and Prince William's grandmother. <strong>MEANING:</strong> <em><a href="http://www.thinkbabynames.com/meaning/0/Alexandra" target="_blank">Alexandra is of Greek origin and means ‘man’s defender.’</a> </em> WHY WE LIKE IT: When it comes to betting on royal baby names, Alexandra is a frontrunner, and it’s no wonder why. The classic name favours royal tradition.

  • James

    <strong>FAMILY TREE</strong>: James Middleton, Kate Middleton's brother. <strong>MEANING</strong>: <em><a href="http://www.thinkbabynames.com/meaning/1/James" target="_blank">The name James means ‘he who supplants’ and is of Hebrew origin. </a></em> <strong>WHY WE LIKE IT</strong>: James is a favourite among the common people. In a YouGov poll of 1,800 people, a whopping <a href="http://www.firstpost.com/world/queen-victoria-or-king-james-peoples-choice-for-royal-baby-name-954263.html" target="_blank">19 per cent favoured James for a baby boy</a>.

  • David

    <strong>FAMILY TREE</strong>: Harry, Prince of Wales (a.k.a. Henry Charles Albert David) and Prince William's brother. <strong>MEANING</strong>: <em><a href="http://www.thinkbabynames.com/meaning/1/David" target="_blank">David has Hebrew origins and means ‘beloved.’</a></em> <strong>WHY WE LIKE IT:</strong> David Beckham <a href="http://www.mirror.co.uk/news/uk-news/royal-baby-name-david-beckham-2054439" target="_blank">suggested his name might be a good fit for Will and Kate’s first child</a>. The soccer star is pretty much British royalty, so who are we to argue?

  • Charlotte

    <strong>FAMILY TREE: </strong>Philippa (Pippa) Charlotte Middleton, Kate’s younger sister. <strong>MEANING</strong>:<em> <a href="http://www.thinkbabynames.com/meaning/0/Charlotte" target="_blank">Charlotte, of Old German origins, means ‘free man.’</a></em> <strong>WHY WE LIKE IT</strong>: Charlotte is <a href="http://www.gmanetwork.com/news/story/317775/showbiz/showbizabroad/royals-waiting-by-telephone-for-kate-s-baby" target="_blank">another favourite in betting circles for obvious reasons</a>. This name has historical royal ties -- Queen Charlotte was King George III’s wife – and it’s still quite popular today, according to online baby name guide Nameberry. It <a href="http://nameberry.com/blog/girl-names-2013-our-100-most-popular-so-far#more-26046" target="_blank">earned second place on the site’s annual ranking</a>, and parents love its “feminine yet grownup” feel.

  • Elizabeth

    <strong>FAMILY TREE:</strong> Queen Elizabeth II, Queen of the United Kingdom and the Commonwealth and Prince William's grandmother. <strong>MEANING:</strong> <a href="http://www.thinkbabynames.com/meaning/0/Elizabeth#qwA1pvxW5c1iTKTx.99"><em>Elizabeth is of Hebrew origin and means God's promise or God is my oath.</em></a> <strong>WHY WE LIKE IT: </strong> Why wouldn't you want to be named after one of the most powerful women in the United Kingdom? Even though sources report that the couple has decided to use <a href="http://hollywoodlife.com/2012/06/11/prince-william-kate-middleton-baby-plans-name-princess-diana/">Elizabeth as one of two middle names</a>, Elizabeth not only honours the baby's great grandmother, but Kate Middleton's middle name is Elizabeth as well.

  • George VI

    <strong>FAMILY TREE:</strong> King George VI was King of the United Kingdom from 1936 to 1952. <strong>MEANING:</strong> <a href="http://www.thinkbabynames.com/meaning/1/George#zuPdDDIpXvFRlxtj.99">Originally of Greek origin, the meaning of George is "farmer". Also there is the story of Saint George, a knight who became the patron saint of England and achieved legendary status after his struggle with a fire-breathing dragon.</a> <strong>WHY WE LIKE IT: </strong> Besides being a dragon slayer, the name George <a href="http://www.britroyals.com/royaltree.htm">goes back to the Royal family's history books since 1660</a>. George VI was also the last male figure in power — this title currently belongs to Queen Elizabeth II.

  • Diana

    <strong>FAMILY TREE:</strong> Princess Diana, The Princess of Wales and Prince William's mother. <strong>MEANING:</strong> <em><a href="http://babynamesworld.parentsconnect.com/meaning_of_Diana.html">Diana is derived from either an Indo-European root meaning 'divine' or from the Latin word 'diviana.'</a></em> <strong>WHY WE LIKE IT: </strong> After Princess Diana's tragic car crash in 1997, Diana would be a wonderful tribute to remember Lady Di. Again, sources say the couple plan on using Diana as a middle name, but we would love to see Diana used as the first name.

  • William Jr.

    <strong>FAMILY TREE:</strong> Prince William, Duke of Cambridge and father. <strong>MEANING:</strong><em> <a href="http://www.thinkbabynames.com/meaning/1/William#kRsY6f1d4xSc9wCW.99">William is of Old German origin and means protection.</a></em> <strong>WHY WE LIKE IT: </strong> Maybe a reason to follow in his father's footsteps, William Jr. may be a suitable name if the couple had a baby boy. Prince William has always been known for his <a href="http://www.biography.com/people/prince-william-9542068">good grades, his love for sports and being a philanthropist.</a>

  • Margaret Rose

    <strong>FAMILY TREE:</strong> Princess Margaret, Countess of Snowdon, was Queen Elizabeth's sister. <strong>MEANING:</strong> <a href="http://www.thinkbabynames.com/meaning/0/Margaret#TXLuZUx8EPt4sFuw.99"><em> Margaret is of Greek origin and means pearl.</em></a> <strong>WHY WE LIKE IT: </strong> Keeping it in the family, we like that fact that Princess Margaret was the Queen's youngest and only sibling. Margaret lived a life of controversy when it came to her love life and divorce, but <a href="http://www.telegraph.co.uk/news/obituaries/1384429/H-R-H-The-Princess-Margaret.html">she was remembered for her affection and love for her family</a>, according to The Telegraph. Plus, so many good nickname possibilities!

  • Frances

    <strong>FAMILY TREE:</strong> Princess Diana's mother's name was Frances Shand Kydd. <strong>MEANING:</strong><em> <a href="http://babynamesworld.parentsconnect.com/meaning_of_Frances.html"> Frances, which comes from old French, means to be free.</a></em> <strong>WHY WE LIKE IT: </strong> Another way to keep a grandmother's name in the family, authors have described her as <a href="http://www.dailymail.co.uk/news/article-305277/Tragic-life-Frances-Shand-Kydd.html#ixzz2DM6a2WrQ">"certainly complicated" but also "funny, warm, intelligent and energetic,"</a> according to The Daily Mail. We also like this name because it could be used both for a baby girl or boy.

  • Victoria (Or Victor)

    <strong>FAMILY TREE:</strong> Queen Victoria <a href="http://www.guardian.co.uk/uk/2011/may/12/queen-elizabeth-second-longest-reigning-monarch">spent 63 years on the throne. </a> <strong>MEANING:</strong> <em><a href="http://www.thinkbabynames.com/meaning/0/Victoria">Victoris of Latin origin and means victory.</a></em> <strong>WHY WE LIKE IT: </strong> Queen Victoria continues to be the family's longest reigning monarch and the longest reigning female in power. As a child, she was known as a "patient rebel" — <a href="http://www.bbc.co.uk/history/british/victorians/queen_victoria_01.shtml">always aiming to be "good" but also very strong-minded, </a>according to Professor Lynne Vallone.

  • Charles

    <strong>FAMILY TREE:</strong> Charles, Prince of Wales, father of Prince William. <strong>MEANING:</strong><a href="http://www.thinkbabynames.com/meaning/1/Charles#m61zdhqFAc4ViKV8.99"><em> The name is Old German and means free man.</em></a> <strong>WHY WE LIKE IT:</strong> Staying true to a father-son bond, royal sources have said that Prince William has <a href="http://www.telegraph.co.uk/news/uknews/theroyalfamily/8165275/Prince-William-Let-my-father-become-King.html">been very supportive of his father and that they share a closer relationship</a>, according to the Telegraph. Who knows, maybe this is a trait that will continue with Prince William's son.

  • Jason

    <strong>FAMILY TREE:</strong> Actually, this name isn't in the family — but it could be. <strong>MEANING:</strong> <em><a href="http://babynamesworld.parentsconnect.com/meaning_of_Jason.html">Jason means the healer.</a></em> <strong>WHY WE LIKE IT: </strong> It may not be part of the Royal family's family tree just yet, but "Fledgling Jason Steed" is <a href="http://www.dailymail.co.uk/femail/article-2162555/Prince-William-30-things-know-Duke-marks-30th-birthday.html">one of Prince William's favourite books, according to The Daily Mail</a>. The story follows an 11-year-old boy named Jason Steed who is destined to save himself and his country from a nuclear threat.

  • Smythe

    <strong>FAMILY TREE:</strong> Okay, we're throwing this one out there but hear us out. <strong>MEANING:</strong> Smythe is <a href="http://www.thinkbabynames.com/meaning/1/Smythe#JcjQC8yGuqc40VS4.99">Old English for 'blacksmith.'</a> <strong>WHY WE LIKE IT: </strong> Kate Middleton has been seen donning a Canadian-made <a href="http://www.huffingtonpost.ca/2012/07/31/kate-middleton-olympic-outfit_n_1723426.html">Smythe blazer several times</a>, including during the 2012 London Olympic Games. And who doesn't like the sound of Smythe for a baby girl? At least it doesn't rhyme easily.
