Hi. I have a 7yr old and a 4 yr old who share a room and they both tend to go to bed around 7.30 after having a book etc. my 7 yr old is still wakened (9.15) and is saying he never gets to sleep. I'm wondering if this is a bit too early or if I should try giving him a book to read in his bed. It's more difficult because they share a room and my 4 yr old likes a night light on. Any advice?
