This is a good place to mention a picture book that I often buy as a gift for children who are about 3-5 years old, the Caldecott Honor winning book Hush! A Thai Lullaby.
There are a lot of things I like about the book that make it a great present. For starters, not many people have it already. The book uses Thai animal noises, not American ones. The rhythm of the words mimics the rhythm of Thai speech. The pictures are beautiful. The story is interesting and designed to lull a child to sleep. And of course, there is the fact that while the mom is busy hushing up all these animals to put the baby to sleep, baby is making a little funny appearance on every page as he crawls all over the place - then finally mom conks out and all the animals but "Baby is wide awake." I think we can all relate!
