KATE TALKS BABY NO. 4!

After years of not-so-subtle hints, Kate Middleton manages to change Prince William’s mind about expanding their family

Kate Middleton was in her element. Learning about infant mental health at the Copenhagen Children’s Museum on Feb. 22, the duchess was surrounded by adorable babies. “It makes me very broody,” Kate admitted to their parents. “William always worries about me meeting under-1-year-olds. I come home saying, ‘Let’s have another one.’ ”

This time was no exception. “As soon as she got home, Kate couldn’t help mentioning it to him again,” a source says of the mom to Prince George, 8, Princess Charlotte, 6 and Prince Louis, 3. “She’s 40 now, so time is running out. She’s really been pushing hard for Baby No. 4. She’s actually starting to wear William down — friends think there could be a big announcement coming later this year.”
