What a good baby!

It seems 5-week-old Charlotte is being the perfect little princess and letting her parents, Prince William and Princess Kate, get a little shut-eye at night.

Doting grandfather Prince Charles talked about the newest addition to the royal family on Wednesday at a tea party with World War II veterans at Clarence House in London.

Geoff Bradley, one of the guests at the afternoon tea, told the Press Association that when he chatted with Charles about grandchildren, “He was saying Princess Charlotte does sleep through the night and it was much easier on mum than Prince George.”

This is probably a relief for Kate and her husband – less than a month ago, a slightly bleary-eyed William admitted that they were enduring sleepless nights with their then-two-week-old baby and an energetic 22-month-old.

“He was saying he’s obviously really enjoying being a father and Princess Charlotte is actually keeping him up – and probably why his eyes are looking a little bit tired,” said Steph Houghton, captain of the England women’s soccer team.
