Uki is my 2 year-old son's favourite thing to watch on TV (actually, the only one he's interested in). The cute and expressive little animals (an insect, rabbit, duck and so on), the classical music that mirrors the feelings of the characters and the stories that are easy for a young child to relate to (playing with a ball, reading a book, being sad and happy again) all contribute to catching his interest.
As a parent, I also enjoy Uki. It is humourous and thoughtful, instead of loud and busy, as most children's programmes are. Each episode is only five minutes long, which means my son does not lose interest until the end. The systematic way in which the episodes are built up is very pedagogical and there is time for the child to wonder and experience the simple action without being rushed. I also really like the fact that the animals in Uki are not marked as male or female - they are just little animals. An interesting aspect of Uki is that there is no dialogue, which actually makes it perfect for talking to your child about what happens in a way that suits your child's language skills and in her/his mother tongue.
