James Middleton has praised his “wonderful sister” Kate as her survey on Early Years care draws to a close.

The Boomf founder, 32, shared a snap of him as a child with his grandparents’ dog and shared the link to his sister’s survey in his bio.

In the post, he said: “This isn’t a post about dogs...brace yourselves....BUT it’s in huge support of my wonderful Sister’s ‘Early Years’ initiative to ask “5 big questions on the under fives”.

“If you have 5 minutes & live in the UK join the biggest conversation on early childhood. Like me even if you don’t have children, your own experiences will help invest in the future of the next generation.”

The Duchess of Cambridge is running a survey in conjunction with Ipsos MORI which aims to spark a nationwide conversation on early years care and development.

It’s become a passion of hers since she married Prince William in 2011 and worked on it for about eight years before launching the survey.

To promote it, Kate travelled to all four nations of the UK, most recently in a surprise visit to Belfast in Northern Ireland and Aberdeen in Scotland.

In Belfast she toured a farm and handled a snake, while in Aberdeen she visited Social Bite cafe and spoke to those whose early years played a role in later life.
