My 4 year old son has started getting up at 5 in the morning and not going back to sleep when I tell him too. To him it's always dark at the moment so he can't understand. He has always been great at sleeping till 7 but not anymore. I feel a night light with different colours to say when it's okay to get up or stay asleep would be great as he would understand that. I have tried googling it but nothing comes up apart from standard nightlights. Any ideas greatly appreciated
