My 20month old has a lot of energy, the only way we can get him to settle for bedtime is to watch moon and me on CBeebies , he focuses on this and calms down and is ready for sleep at the end , I would love to replace this with reading books , he will sometimes sit on my lap and read at other times and points out pictures in the books , but at bedtime he just flies around if we try to read , when will a child actually be able to focus enough to use a book to settle to sleep ?
