Princess Kate's plan for baby No. 2 inside People Magazine January 2015 edition

A lot of things are going to change when Kate Middleton welcomes baby No. 2  and she's doing everything she can to prepare before her due date in late April.

At the top of her to-do list: making sure to spend plenty of one-on-one time with her firstborn, 17-month-old Prince George.

"She will be mindful that this will be one of the last opportunities for sole 'George time,' " maternity nurse Sarah Dixon, who has worked with friends of Kate and Prince William, tells PEOPLE in this week's cover story. 

Prince William and Kate Middleton may hire a second nanny after the new baby's birth. And Kate's mom Carole often steps in as caregiver when her daughter is occupied with royal duties.
