Cyw and friends will feature in the new S4C service
A new Welsh language service for children of nursery age has been unveiled by broadcaster S4C.
The service, which was launched at the Urdd National Eisteddfod in Conwy, starts on 23 June on S4C's digital channel, S4C Digidol.
There will be six-and-a-half hours of programmes for children of nursery age, compared to one hour currently.
It is the first stage of S4C's plan to introduce a separate Welsh language channel for children and young people.
The new service - entitled Cyw, or Welsh for chick - is accompanied by a bilingual website which will feature games, activities and information for parents.
Many of the programmes will be available to watch online, with English subtitles available for most shows.
"The launch of Cyw is one of the most important developments in S4C's history and reflects the channel's commitment to the children of Wales and their families," said S4C chief executive Iona Jones.
Sam Tân, or Fireman Sam, is part of S4C's plans
"I'm confident this significant expansion will reinforce the good name S4C and its independent producers have in the field of children's programming, in Wales, the UK and internationally."
Cyw, which replaces S4C's former nursery brand Planed Plant Bach, will feature children's presenters Rachael Solomon and Gareth Delve.
Programmes will include song and dance show Triongl, live-action series Pentre Bach and animated favourites Sam Tân and Sali Mali.
The programmes will be broadcast on weekdays, from 0700 to 1330.
S4C is due to become a stand-alone Welsh-language channel after digital switchover, with no programmes being re-broadcast from Channel 4.
