My son loves the "Llama, Llama" books. We now have most of them and my son is constantly asking me to read them to him! This one is cute. It talks about the little llama wanting his mama. After he throws a fit and convinces himself that he is alone, mama lama shows up. She explain to him that she loves him very much, but is busy and can't always be right next to him. The book has adorable rhyming in it which my son loves. I also use this book to teach my son that just because mama is not in the same room with him doesn't mean that she isn't nearby. I use it as a lesson tool! :-)
