K-Mid gave birth to Princess Charlotte just 6 weeks ago

She gave birth to her second child just SIX WEEKS ago but Kate Middleton is already back in her Topshop skinny jeans.

And we think we know how.

The Duchess of Cambridge enjoyed a day out at the polo with her nearly two-year-old son Prince George and we feel breathless just watching her trying to keep up with him!

The cute toddler was pictured climbing up a grass verge, kicking a football and chasing after his friends. No wonder Kate, 33, is so fit. As any mum-of-two will know, sitting at home with your feet up watching a boxset feeding your newborn goes out the window second time around.

Kate was dressed in a pair of Topshop skinnies, teamed her trusty ME+EM striped top, £48, with her favourite Sebago shoes, £89.99.

Prince George looked dapper in a pair of blue shorts, a light blue cardigan and matching Croc sandals.

There was no sign of baby Princess Charlotte, leaving Kate plenty of time to lark about in the grass with her first born. And she appeared to be enjoying every minute together.

Proud Kate was at the Beaufort Polo Club to watch husband Prince William and his brother Prince Harry take part in a charity match in the Festival of Polo.

They were joined by Zara Phillips and her husband Mike Tindall with their daughter Mia Grace, as well as Zara’s brother Peter, wife Autumn Phillips and their children Isla, three, and Savannah, six.

William, 32, and Harry, 30, were relatively dressed down in chinos and polo shirts – a world away from the previous days formality at Trooping the Colour.

How Kate Middleton is dressing Prince George the same as Princess Diana dressed Prince William as a kid
