Eight little rays of sunshine are heading off on holiday to Turkey.

This special edition of the brilliant observational show sees the children experience new things in new places under the close observation of their mums and dads, teacher Kate and experts Dr Elizabeth Kilbey and Professor Paul Howard-Jones.

A huge part of the one-off show is how the fantastic five-year-olds cope in unfamiliar situations.
