Pippa Middleton takes a stroll with newborn daughter Grace in her pram in Chelsea

Pippa Middleton wrapped up warm as she took a stroll with her newborn daughter in London earlier today. 

The Duchess of Cambridge’s sister, 37, who welcomed her second child Grace Elizabeth Jane with husband James Matthews last month, sported a long-line burgundy coat with a fluffy collar during the walk this afternoon. 

The mother-of-two donned a matching maxi skirt but kept it casual with white trainers in Chelsea, west London. 

Grace was born in the early hours of 15 March, weighing 6lbs 7oz. Announcing the birth just hours later, a source told Hello!: ‘Mother and baby are doing well. She’s perfect, everyone is overjoyed at such a happy arrival.’

Pippa wore her long brown locks loose around her shoulders and kept her makeup minimal for the outing. 

The new mother could be seen gazing down at her newborn and tending to baby Grace as she reached into her navy pram. 

Pippa and James already share a two-year-old son Arthur, who joined his mother for a walk at the end of last month. 

He clung onto the handle of the pushchair and proved to be the doting big brother as he gave his mum a helping hand.

Pippa looked the epitome of ‘mummy cool’ on the walk, having welcomed her daughter  in the early hours of March 15, weighing 6lbs 7oz.

Grace’s middle names are a nod to her grandmothers, Carole Elizabeth Middleton and Jane Matthews, while Elizabeth might also be a subtle acknowledgement of the family’s royal ties. 

Rumours of Pippa’s pregnancy first swirled shortly before Christmas when Page Six reported the couple were expecting another baby. 

A source close to the Middleton family told Page Six in December Kate’s sister was expecting, saying: ‘Pippa and James are thrilled, it’s fantastic news amid a difficult year. The entire family is delighted.’ 

Pippa never commented on the pregnancy and instead kept a low public profile.

The Duke and Duchess of Cambridge will no doubt be delighted with their new baby niece, which came in the wake of the fallout of Prince Harry and Meghan Markle’s bombshell Oprah interview.

As well as the Cambridge children, Grace has two cousins on her father’s side of the family: Theodore Frederick Michael, two, and Gigi Margaux Matthews, nine months, the children of Made In Chelsea’s Spencer Matthews and his Irish model wife Vogue Williams.

Kate and Pippa’s brother James Middleton, 33, is engaged to Alizee Thevenet.

Pippa and James enjoy a close relationship with both families. The Middletons enjoy holidays with the Matthews clan at the family’s exclusive Eden Rock St Barts resort, proving just how well they all get on.

Pippa and James also raise their children with the support of their parents, with Carole recently telling Good Housekeeping that she is a hands-on grandmother.

‘I want to run down the hills, climb the trees, and go through the tunnel at the playground,’ she said. ‘As long as I am able to, that’s what I’ll be doing. I cook with them, I muck around dancing, we go on bike rides.’

She said she would hope to pass down a love of the countryside and hoped she could help them ‘really see the value of being able to appreciate nature and be active outdoors.’

Describing herself as ‘very family-orientated’, Carole said she has always ‘tried hard to be a listening grandmother and mother-in-law’ to Prince William, 38, and Pippa’s husband James Matthews.

Pippa and James tied the knot in 2017 at St Mark’s Church in Englefield, the estate of former Conservative MP Richard Benyon.

In 2018, Pippa welcomed baby Arthur in the Lindo Wing of St. Mary’s Hospital, the same place where sister Kate gave birth to all three of her children.
