Women have compared their own post-natal pictures to those of Kate Middleton who emerged in full make-up and high heels hours after giving birth.
When the Duchess of Cambridge emerged from the Lindo Wing of St Mary's Hospital, Paddington, the world's paparazzi was waiting to snap the first shots with her new son.
She looked serene and well-groomed in a red shift dress and nude heels.
Mothers took to Twitter to compare their own post-birth experiences, observing that expectations of Kate seem impossibly high.
BBC business and consumer correspondent Nina Warhurst posted a picture comparing her post-natal look with the Duchess of Cambridge's, writing: "Me and Kate 7 hours post-natal.... I'm the one on the right, in case you're wondering..."

"Kate Middleton looks better 7 hours after giving birth than I do 7 hours after sleeping 12 hours," observed comedian Sarah Cooper.
"How does she look so good," asked one woman.

I didn’t get out of bed for 15 hours post birth, let alone put high heels on and went outside! pic.twitter.com/gmbOiEex1g

The 8lb, 7oz Royal baby was born at 11.01am on St George's Day. He is fifth in line to the throne and is younger brother to four-year-old Prince George and Princess Charlotte, who turns three next week.
Prince Charles told reporters it was a "great joy" to be a grandfather again, as the couple settled their child in at Kensington Palace.
He said: "It is a great joy to have another grandchild, the only trouble is I don't know how I am going to keep up with them."
Meanwhile speculation mounted over the name the Duke and Duchess will choose for their third child.
Arthur remains the favourite name for the Royal Baby with most bookmakers slashing odds to 2/1 late on Monday and into Tuesday, followed closely by James and Albert.
