Kate Middleton and Prince William are parents of three children; George, Chalotte and Louis. They have shown that they like to have a large family, but even though they have not said they are ready to expand, people are convinced that baby number 4 is on the way. Some signs from Kate have prompted the whole world to talk about a possible pregnancy for the Duchess of Cambridge.
Kate appeared accompanying the children on the first day of school. What was striking was a change in the appearance of the Duchess. She had dyed her hair color and changed their hairstyle. Kate has been experimenting with appearance ever since she was in her first months of pregnancy, so that attention is focused on the appearance and not on her belly or the extra pounds.
Also, another sign that has raised even more doubts is that the Duchess has closed all meetings on her agenda. She wants to take a break and according to people this could be a sign of pregnancy. As all three of the Duchesses' pregnancies have been complicated and she's had a lot of worry the first few months, this vacation period has made everyone think Kate might be pregnant.
A source has indicated that Charlotte has been heard telling schoolmates that her mother will give birth to another daughter.
