As someone who dated and lived with someone who had a two/three year old for a year, those two ages are absolutely difficult to manage. Nothing you do seems to work, they refuse to go to sleep and just wanna stay up all night watching TV and throw a fucking fit when you turn it off and do not stop screaming. You think they would tire themselves out and eventually fall asleep...NOPE, screaming for HOURS on end. Throwing things, yelling at you, those ages are rough so I don't blame you.
