The Secret Life of Brothers and Sisters

In this first episode Tia, Tyler, Theo, Lola and Taylor - who are now five years old - return, alongside great friends Alfie and Emily, who are now six. As before, scientists observe their every move.

More of the best-loved children return in this second episode, which explores what it's like to be a younger sibling. Charlotte, who's five, and six-year-old George are among some of the younger children all going on a camping holiday with their older brothers and sisters and some new friends. How do they assert their independence with their dominant older siblings around?
