What a cutie! Jools Oliver shows off 7-week-old Petal Blossom Rainbow on Thursday at The Big Toddle in London.

The Barnardo’s Big Toddle is the UK’s biggest charity event for children under the age of 5 — each year, up to half a million children take part in a short sponsored walk to benefit children’s programs across England.

Petal, who arrived April 3rd, is the third daughter for Jools and chef husband Jamie Oliver. The couple are also parents to Daisy Boo, 6, and Poppy Honey, 7.
