I am trying to get my 18mo old to sleep later in the mornings (currently 5.25am) and am going to start using the 'no getting up til the light goes on trick'. But how exactly do you explain this to a 18mo old? This moring i stayed with her until get up time (when i switched the light on and made a big fuss of 'oh look the light is on this means it is get up time') do i need to do this for a few mornings until she gets the idea or will going into her room when she wakes up only make things worse in the long run? Any advice welcome. Thanks
