How pregnant is the Duchess of Cambridge?
Not so pregnant that we should know about it. The couple had planned to announce the baby on Christmas Day, according to "royal sources", but with the Duchess's admission to hospital the couple took the "reluctant and difficult" to decision to confirm the news before the tabloid press or Twitter did. Most women prefer to keep a pregnancy secret until after their 12-week scan; Kate is thought to be about eight weeks pregnant.
What is hyperemesis gravidarum?
An acute form of morning sickness in which the woman suffers such extreme nausea and vomiting that she is unable to hold down fluids, and can become seriously dehydrated. The condition usually recedes between three and four months, although in a minority of cases it can continue throughout the pregnancy.
How many people have to die before the baby becomes monarch?
Three – the Queen, Prince Charles and Prince William. Though there is always the possibility of an abdication, or that odd constitutional arrangement that people occasionally talk about where Charles would agree to let the succession skip a generation, for reasons unexplained.
Amid all the joy, spare a thought for Viscount Severn, who, although you have never heard of him, is ninth in line to the throne. The four-year-old son of the Earl of Wessex will find himself pushed to 10th by the new arrival.
What if it's a girl?
Lucky baby. Princess Anne, despite being the Queen's second child was bumped down the line not only by her two younger brothers but even their female offspring (Beatrice is currently fifth in line to the throne; Anne is 10th.
Thanks to a change in the law of succession, announced last year, royal children will be treated the same, so the baby, girl or boy, will become third in line to the throne, and cannot be dislodged by younger siblings.
What are the chances?
We're going to make a bold prediction here and say roughly 50:50. A Swedish study in the Lancet in 1999, however, found that women with hyperemesis gravidarum were slightly more likely to be carrying a girl. William Hill, meanwhile, is offering 5-6 that it's a boy or evens if it's a girl.
Why do some people think it might be twins?
The risk of developing hyperemesis gravidarum is slightly increased in twins or triplets.
And if it is, which one would be king or queen?
The first one out.
What will be the baby's family heritage?
One of the child's great-grandparents is queen of 16 sovereign states and head of the 54-nation Commonwealth. Another of its great-grandparents was a lorry driver called Ron from Southall in west London. The baby's future great-uncle Gary Goldsmith lives in Ibiza in a house called La Maison de Bang Bang. Another great-uncle is Prince Andrew.
Where will they live?
They are unlikely to be short of space for a nursery. The royal couple have lived in a private farmhouse in Anglesey for much of the time since their wedding, but are awaiting building works to be completed on a 21-room suite in Kensington Palace, formerly the residence of Princess Margaret.
But what will she wear?
The Daily Mail's Liz Jones kicked matters off by advising the Duchess "to carry on as though nothing has happened", sticking to her favourite "princess-line coats, tailoring and colour". For evening events, she should embrace "strapless empire-line dresses", and you can get fabulous bootcut maternity jeans these days with stretchy waists.
Was Kate's new fringe a secret sign of her pregnancy?
What will be the baby be like?
Observers are predicting a birth in early to mid-July, making the baby's star sign Cancer. Cancerians "tend to be intensely private but deeply compassionate and caring". The Daily Telegraph reported on Tuesday that the Duchess "'will give birth to a girl' who will grow to 5ft 10ins, studies suggest". Bookmaker Paddy Power said it had taken "hundreds of pounds" on the baby being ginger, like Prince Harry.
What other random facts do I need to know about this baby?
The Queen's gynaecologist, who is treating the duchess, is Alan Farthing, the former fiance of the murdered TV presenter Jill Dando.
The law change permitting girls to have the same rights of succession as boys will have to be accompanied by legal amendments in all 16 nations where the Queen is head of state. The process is being overseen by a "Realms working group" led by the New Zealand prime minister, John Key.
The baby's future maternal grandparents, Carole and Michael Middleton, are "over the moon", according to John Hayley, landlord of the Old Boot Inn in Stanford Dingley, the Middletons' local.
