Sounds like he's overtired and overstimulated - he's got too much to process and he's staying awake to deal with it all. I would cut out all the taking him to places and 'trying to wear him out' - it has the opposite effect on toddlers. They need calm environments and lots of sleep. How's his daytime napping?
I cannot get this little MONSTER to go to sleep, i put him in his cot his screams and makes himself sick, i put him back in our bed he lies there messing around, i play with him all day i take him places to "wear him out" im so tired its 10.45pm for gods sake!!
What the fuck have i done wrong? Ive messed it all up!
