Prince William and Kate have no doubt been toasting the arrival of their third child, but the couple also have another very special reason to celebrate this weekend. The Duke and Duchess are marking their wedding anniversary on Sunday 29 April – seven years since they tied the knot at Westminster Abbey, London in front of 1,900 guests. As they do every year, the couple will celebrate in private, but plans may be put on the back burner this weekend now that William and Kate have a newborn to care for.

The doting parents will have their hands full looking after their four-day-old son, as well as Prince George, who turns five in July, and Princess Charlotte. Kate may also be putting the finishing touches to her daughter's birthday celebrations; Charlotte turns three on Wednesday.

The baby's name is expected to be announced imminently, with several reports suggesting that Albert, Arthur and Alexander are the favourites. During William's public engagement on Wednesday when he attended the Anzac Day service, the Prince was asked if the baby's name is Alexander. William quipped: "Alexander? Funny you should say that." He added of his wife and their new child: "They're very well thanks," saying that everyone is "in good form, luckily". The future King added: "Sleeping's going reasonably well so far, so he's behaving himself, which is good."
