While George doesn't turn one until July, Pippa's website The Party Times is already publishing features on just how to celebrate... And recommending "loads of cute 1st birthday ranges at Party Pieces" from the mail-order company owned by Kate's parents, Michael and Carole Middleton.
"We'd also advise keeping the party short - two hours maximum - to maintain attention spans. Although it's an exciting day for you, your one-year-old won't expect too many surprise birthday party games and activities.
"Keep fun simple so as not to over-excite them." While we doubt K-Middy and Prince William will be hosting a party quite like The Party Times suggests, the Middletons could well be cashing in on the first anniversary of his birth.
