The timing of my own July born's arrival was certainly not planned (let's just say he was a rather longer-awaited baby than average and as such I was happy to have him whenever) but his birth month turned out to be a real bonus.
Why? Well, first up, when you're up at 1am (and 2 and 4 and 5...) feeding and sorting out your newborn's nappy changes, you're far less likely to be shivering your way down the corridor in your nightie in June, July, August. (I imagine palaces, even with modern central heating, can still be a little draughty, of a winter's night.)
Come daytime, it's infinitely more bearable going for that stroll and getting out of the house/palace when the sun's shining. But be warned, Kate, pushchair brakes are a bugger to engage in a pair of flip flops.
Whilst out, you needn't worry your little prince or princess might fall victim to a bout of hypothermia at the slightest whiff of a breeze. Indeed when you do want to leave the palace, you won't have to spend 20 minutes beforehand wrapping junior in so many layers of snowsuits, bodysuits, vests and blankets that it's hard to spot them underneath it all. At this time of year, a nappy and bodysuit will do the job just fine, even for royalty.
If you're stuck for something to do, because let's face it, days with a newborn can drag on a bit and you might not feel like heading to your usual round of engagements with bags the size of Prince Charles' Rolls under your eyes, you can stay on the sofa and pop Wimbledon on the telly (as close as you'll probably get as newborns aren't known for respecting calls for 'quiet please' from the umpire or anyone else for that matter).
When it comes to birthday parties, (planned by Auntie Pippa one presumes) it will be far easier to hold them outdoors on the palace lawns in July. (Try asking Great Grandma if you can have the bash at Buckingham - sure to impress the other mums from nursery.)
You won't have to cower inside on a dull December day, trying to keep 20 small, deeply over-excited people entertained in one room (even if it is a sizeable state room rather than the average three bed semi's lounge).
As time passes and the new royal grows up, it might well be that the effect of his or her month of birth brings other advantages: apparently summer borns have a more positive outlook on life. Cue particularly jolly King's or Queen's speech come Christmas Day in 60 years' time then.
Of course, naysayers will point to research that summer babies tend to struggle more at school since being in the same class as children nearly a year older and with capabilities to match, can be a blow to confidence. This could, in theory at least, harm the young royal's job prospects. Fortunately all those autumn born kids aren't going to be able to compete with the third in line to the throne when it comes to the job of future King or Queen.
Are you expecting a July baby? Or have you had a summer born baby?
