....but have 
I know this has been done over so many times but i think theyre funny and cant sleep.
I would...
-never let DS eat chocolate ect.. He would live off fruit and veg 
-not watch tv alot. We watch frozen at least once a day.
-never have him in our bed
-never let him have his own way to stop a meltdown 
-not nap when he naps so i can get stuff done in the house. (He is one next week and i nap once a day with him still)
