Can we all just take a minute to appreciate leap 6? Current leap 6ers and past.
DS seems to have entered it early and the only way I can describe it is HELL.
He will not nap.
He will not go to sleep in the evening.
He crawls around his cot constantly then gets stuck/bumps his head and cries.
He doesn't want to be put down.
He doesn't want to be picked up.
He sleeps really lightly and keeps turning onto his front to rock on all fours.
He keeps arching his back, going rigid and throwing his head back.
He bops on and off while BF.
He will not cosleep - my usual go to when he's being difficult.
He is just MISERABLE and quite frankly so am I!! 
Oh the joys!!
