Its just been a few days that the Royals have announced the big baby news of Duchess of Cambridge pregnant with her second child. Latest reports however reveal that Kate Middleton has plans to expand her family beyond two children and wants to have her third child before she turns 35-years-old. The Duchess plans to give Prince George at least two siblings just like she had when she was a child. The Duchess is currently 32-years-old and it gives her three more years to try for yet another baby.

Friends of the Duchess revealed to The Telegraph newspaper that though Prince William is happy with two children, the Duchess wants to have "at least" three children in the royal household. Kate is just 20 months older than her sister Pippa Middleton and the two sisters share a good bond together along with their brother James, who is and less than five years older than Kate.

Prince George's sibling will be born in either April or May 2015 and the two will have almost exactly the same age gap as Kate Middleton and Pippa Middleton have. Another reason why Kate planned her second baby now is that she is already 32-years-old and women's fertility suffers a decline after she turns 35. Kate will be 33-years-old when she has her second baby, leaving her with two years to try for a third child, reports the newspaper.

Royal bets are high on weather the Duchess will have twin babies, a boy or a girl. The general sentiment in the bookie market is that the Duchess will have a baby girl whom she will either name Elizabeth or Diana, various websites are reporting.

Prince Charles, grandfather to Kate and William's first baby is hoping that little Prince George has a sister this time. "It's wonderful to have another one. I'm happy I'm going to be a grandfather again. I'm looking forward to it - but I hope it will be a girl this time," said Prince Charles to The Telegraph when he was congratulated for the news.

"It's not here yet! No, it's wonderful, we are very happy. It's splendid, very exciting," said the excited grandfather.
