Kate Middleton stopped by The Fostering Network's headquarters in London on Friday, and not only did she spend her morning visiting with foster caregivers and children at the center, but she gave us a peek at her growing baby bump in a beautiful brown dress. Kate stepped out yesterday at the Clore Art Room at the Barlby Primary School in London, and her last appearance before that was just around Christmas.

The Kensington Royal Instagram account posted several pictures of Kate and wrote, "Thanks to all the carers, children and staff at the Fostering Network who shared their stories with The Duchess of Cambridge this morning!"

Lucy Peake, the director of development at The Fostering Network, added in a statement, "A visit from The Duchess helps to shine a spotlight on fostering and the need for more foster carers, particularly to look after teenagers, disabled children and groups of brothers and sisters. We are very grateful to her for her interest, and know that the foster carers and care leavers attending our event today are excited to be sharing their experiences and stories with her."

Still no word on whether Prince George will be getting a little brother or sister, but the palace previously confirmed that Kate is due in April.
