The duchess' tour of Baby Basics UK in Sheffield highlighted her efforts spearheading a donation drive which has seen shops like John Lewis, Marks & Spencer, Sainsbury's and Tesco give more than 10,000 new goods to baby banks across the country.
During the event, Kate put on a floral face mask and described how she wept after a trip to a baby bank, which provides essential items to mothers in need like nappies and infant clothes, similar to the project in Sheffield.
She said: "It can get very emotional.
"I remember a couple of the families I met from King's Lynn and I went home and literally burst into tears, their stories were so moving. The struggles they have gone through, the bravery they have shown ... in extraordinary circumstances.
"Helping their families through extraordinary times."
