Kate Middleton brought attention to the Shaping Us campaign at St. John's Church of England Primary School in East London.

She talked to students who were 4 and 5 years old about feelings and growing up in a safe place.

The kids held their favourite stuffed animals as they watched a claymation movie from her new ad for early years.

Kate asked the group what they thought about the short video, swimming, birthday cakes, and ice cream.

They also talked about the nice things people have done for them.

On Monday, Kate gave a speech at BAFTA that was a big step for the Shaping Us campaign.

On Tuesday in Leeds, she set up an Instagram page for The Royal Foundation Centre for Early Childhood.

Kate has been slowly putting together a group of advisors to help the Centre spread the word about how important a child's first five years are.

People who know Kate well say that her public duties will be shaped by the work she does now for the next 30 years.
