Have baby, will travel: Una Healy shows off baby Aoife's first passport

<p> <strong>Maternity leave length:</strong> 10 days with Ava, 10 weeks with Hero<br /> <br /> When her now toddler, Ava was born, glamorous girl Myleene headed back to present her radio show just 10 days later. She took a bit longer off when little <a href="http://www.parentdish.co.ukphpmyadmin.parentdish.co.uk/2011/03/26/myleene-klass-has-baby-girl/" target="_blank">Hero</a> arrived on the scene, but only <a href="http://www.parentdish.co.uk/2011/06/08/myleene-klass-why-i-have-gone-back-to-work-10-weeks-after-baby-hero-born/" target="_blank">10 weeks</a> in total. The reason? She didn&rsquo;t want the world to forget her.<br /> <br /> &lsquo;Whether it was six months or six weeks, it was never going to be easy,&rsquo; admitted Myleene at the time. 'My fianc&eacute; Gray is always saying, 'You need to go easy on yourself.' Last week, I had terrible mastitis and Gray tried to get me to relax. But I'm petrified showbusiness will leave me behind, as it has before.&rsquo;</p>

<p> <strong>Maternity leave length:</strong> Six weeks</p> <p> A month and a half into motherhood, Gisele waved goodbye to life as an at-home mum to Benjamin, and headed back to her modelling career, shooting a promo for a fashion brand. She was apparently overheard saying that although it wasn&rsquo;t long after the birth, she was &lsquo;in shape as always.&rsquo; Urgh.</p>

<p> <strong>Maternity leave length:</strong> Seven weeks<br /> <br /> Less than two months after giving birth to her fourth baby, Lou, Heidi squeezed herself into a leather skirt and filmed a haircare advert, showing off her impossible post-baby curves, without a dark circle under the eye or stretch mark in sight.</p>

<p> <strong>Maternity leave length:</strong> Four months</p> <p> After wading into the maternity leave row by lashing out at <a href="http://www.parentdish.co.uk/2010/11/04/denise-van-outen-criticises-natalie-cassidy/" target="_blank">Denise Van Outen</a> for heading back to the office, Natalie Cassidy was the pot calling the kettle black when she signed up for a reality show following her life as a new mum. She set about <a href="http://www.parentdish.co.uk/2011/02/01/natalie-cassidy-takes-baby-eliza-to-work-despite-criticising-working-mums/" target="_blank">promoting it</a> just a few months after welcoming baby Eliza, with appearances on TV chat shows and pages and pages in celeb magazines. As you can imagine, Denise <a href="http://www.parentdish.co.uk/2010/11/04/denise-van-outen-criticises-natalie-cassidy/" target="_blank">saw red&hellip;</a></p>

<p> <strong>Maternity leave length: </strong>Three days</p> <p> Apprentice star and businesswoman <a href="http://www.parentdish.co.uk/2011/02/08/karren-brady-sudoku-in-bed-holidays-and-how-you-can-never-be-too-competitive/" target="_blank">Karren </a>took an unimaginable three days of maternity leave when she welcomed her first baby, now teen, Sophia. Admitting it wasn&rsquo;t an ideal situation, Karren took a much more relaxed approach with her second child, Paolo. &lsquo;That was a mistake. When Paolo was born I took more time off and worked from home,&rsquo; says Karren. &lsquo;I tried bringing both children into the office but that didn&rsquo;t work out. I had to have full-time help in the end.&rsquo;</p>

<p> <strong>Maternity leave length:</strong> Three weeks</p> <p> Mum of three Katie hit the headlines when she appeared on the Apprentice a few years ago. She wades into mum debates in the press regularly, recently speaking out about maternity leave, encouraging new mums to head back to work as soon as they want to: &lsquo; I took 'micro maternity leave' - you're pregnant, you give birth, you go back,&rsquo; admitted Katie. &lsquo;Work gives a sense of normality when you don't even recognise your own body.&rsquo;</p>

<p> <strong>Maternity leave length:</strong> 12 weeks<br /> <br /> Model and glamour puss Miranda was back in her cossie and on the runway just three months after giving birth to her first baby with husband, Orlando Bloom, super-cute Flynn. She also, somehow, managed to shift two stone in 12 weeks ready for her new-mum close up. Not that we couldn&rsquo;t do it too if we really wanted to&hellip;</p>

<p> <strong>Maternity leave length:</strong> Four months</p> <p> Not too bad compared to other celebrity mummys, but four months still seems a little quick to us, and Kym&rsquo;s Twitter followers clearly agree. She was <a href="http://www.parentdish.co.uk/2011/07/14/kym-marsh-in-twitter-outrage-over-working-mums/ " target="_blank">blasted </a>on the social networking site for heading back to the cobbles and filming for Corrie so soon after giving birth to<a href="http://www.parentdish.co.uk/2011/03/24/kym-marsh-gives-birth-to-daughter-five-weeks-early/ " target="_blank"> Polly, </a>but she wasn&rsquo;t having any of it, responding to her critics with the tweet: &lsquo;It's called working.....or should we not be working when we have children?? How dare we provide for our kids! Idiot.'</p>

<p> <strong>Maternity leave length:</strong> Three weeks</p> <p> Nicole headed back on to the set of the film, Australia, just a few weeks after giving birth to her first baby, Sunday Rose. The new mum was clearly not one for rest and relaxation at home, admitting after her quick return: &lsquo;I&rsquo;d just given birth, so I was like, &lsquo;I&rsquo;m still a woman &mdash; I want to do this film! And I have a life other than feeding this baby.&rsquo; When you give birth you&rsquo;re itchy to get back to work, you want to feel that life still goes on.&rsquo;</p>

<p> <strong>Maternity leave length: </strong>Two weeks<br /> <br /> Just a fortnight after welcoming baby Betsy, Denise was back at work, doing the rounds on TV, radio and promoting her maternity clothing range. Confidently admitting she was ready for action, Denise said:&nbsp; &lsquo;I am not taking any time off. I am working. I worked two weeks after I had Betsy, so I have carried it all on, really. I work at least three days a week and my mum is helping out.&rsquo;<br /> <br /> Of course then it all kicked off when <a href="http://www.parentdish.co.uk/2010/08/24/pregnant-natalie-cassidy-slates-denise-van-outen-for-returning-t/" target="_blank">Natalie Cassidy criticised her</a> for heading back to the day job so quickly&hellip;</p>
