And baby will make four - the Cambridge family will be welcoming a new member in 2015
The baby is due sometime in 2015. Royal pregnancies are usually announced around the three month mark although Kate's first foray into motherhood came to everyone's notice a little sooner as she suffered severe morning sickness. She is poorly with hyperemesis gravidarum again but being treated at Kensington Palace rather than in hospital this time round. There is no official word on a due date but sometime between February or March would seem most likely. And what is definite is that whenever it is there will be huge interest - royal baby number two mania begins now.
