Our seven year old son has always been up with the birds (in WA that is anywhere between 4.30am-5.00am). On the plus side, he goes to sleep at 6.30pm without any trouble. We have tried over the years to discipline and or to reward him in this area - to no avail.
He has learned in the past two years to at least stop coming to visit us in our room and wake us up and now prefers to read in bed or play quietly in his room.
The trouble is he is then cranky and disobedient as the day and especially school week drags on.
We have also tried putting him to bed later however he still wakes up at the same time every morning.
We would welcome any suggestions you have.
