The Prince William and Kate Middleton pregnant news announcement came sooner than planned for the royal couple, according to palace sources. Kate Middleton has been in the hospital since the announcement of her pregnancy due to severe morning sickness called hyperemesis gravidarum requiring rest and hydration. This acute morning sickness and required hospital stay was the reason why the Kate Middleton pregnant story went public when it did.
The wife of Prince William was admitted to the hospital just after the Kate Middleton pregnant announcement. This sparked speculation the news of the royal pregnancy was released earlier than scheduled as it would have been difficult to otherwise explain away the extended Kate Middleton hospital stay. Sources inside the palace confirmed to several media outlets that this was the case.
