wakeing at 5.30am

[childern]

My freind has 2 children near 4 and one who is 2.5, they are wakeing up at 5.30 so by 9am they are tired. Has any one had the same thing happen! her eldest has said to day that he won't sleep because his eyes keep geting wet when shut did tell him that they need to he won't even sleep in the day he is worn out you can see it PLEASE has anyone got any tips for her to try!!!!!!!!!

reward/incentive charts for staying in bed till a certain time. Digital clock where they cant leave the room until a certain time. Nightlight, fairy lights, etc on a timer which signals when they can leave the room. They might not make her lo's sleep any later but should teach them that even if they are awake they cant disturb anyone else.

She has tryed the alarm clock worked for a little while.Its like her little lad is scared to sleep so he won't untill he just can't keep his eyes open any longer.
