My 4 year old used to sleep through till 7am or later. Since starting school 2 months ago she continually wakes between 5.30am and 6am. We thought it was the excitement of full time school and exhaustion would kick in. Despite being dog tired in the evenings, she still wakes up at this new early hour. Illness, half term hols and clocks going back haven't broken the pattern. Bedtime routine is the same, calm and in bed by 7pm. Have tried different bedtime patterns but made no difference. So gone back to normal one. Any thoughts as to why this is happening and if there is anything we can do to encourage longer sleep as she used to before starting school full time? Thanks!
