The micro maternity leave was a staple of women’s lives right up until 1992, when the statutory six weeks off was raised to 14.

Current law means new mums can now take up to a year off after having a baby in the UK, but it seems the trend for many women in the world's spotlight is to take as little time as possible.

This week, Countdown ’s Rachel Riley returned to set just 11 weeks after welcoming her first child Maven Aria into the world with husband Pasha Kovalev .

The mathematician beamed as she took Maven to Channel 4 ’s studios, and documented the adorable moment on Instagram .

Rachel, 34, and Strictly Come Dancing star Pasha, 40, took time away from their newborn bubble to visit the set as the star got back to work.

Jumping right back in the saddle on the show, she captioned her post: “First block back at work done and dusted and I can still sum post baby... phew!

“Mave was busy melting hearts and Pash is a hero.

“The eternal on screen pregnancy has just a month to go! Now back to family time for us, we’re really loving it.”

Looking sleek and stylish in a preppy white polo dress from Sandro, fresh faced Rachel looked like she hadn’t lost a wink of sleep in her first few weeks as a mum.

So as Rachel buys into the micro maternity trend, Mirror Online looks at other boss-mums who’ve embraced motherhood and lauched themselves straight back into work post-birth.
