7 months of NO SLEEP

Hi all, My child is 7 months an his sleeping pattern is all over the place.I just changed it around, he goes to sleep at about 10-11 pm an wakes up bout 1 or 2 am an stays awake 4 a couple hours, he wants to play. It get pretty hard, Im used to it, but slowly falling apart.

As i always say i am no expert by any means but don't let him play at night. Have all the lights off, just enough to see. It may be trying at first and even a lot of crying but between 3 and 10 days he should get the idea.
He is well old enough now to know the difference between day and night. Also during the day if he sleeps make sure the room is bright!
Just a few ideas, i hope they might help!

PLEASE!
Go to a sleep clinic!!!! Or if you can't do that, go to your closest child health clinic - you don't have to live like this!

Seek help, and remember you are not alone!
