For some reason, my sister left me her son and daughter to take care of. Her daughter took off alone and managed to open a guest account in my laptop. She's playing Candy Crush (I didn't even know I had this game in my laptop). Her brother started crying... a lot. He keeps crying and wailing Mama while while leaning on the door almost like Haise Sasaki was in Cochlea. I kept telling him mommy was gone, but that added more gasoline to the fire. I patted his head like I once read in a WN, but he bit my hand. I gave him some my supposedly exotic anime figure collection and some Rubik's cubes (since he didn't want to play with his toys) and he threw them at the door. He's punching the door with strenght I've never seen a 3 year old exerted. I'm worried the neighbours might call the cops on me.
Can't help you there mate, sadly I have no clue how to do these things, what I would say is, perhaps try to find some subreddit on reddit which deals with similar situations in a serious way, and get your knowledge there instead of on a forum of people who read novels all day, while it's possible that some might apear who are genuinely able to tell you what to do, it's entirely likely that many of the replies will be bs ones just for laughs.
you should play with the son and daugther,, do not let them play computer as it would destroy their future. be a good Onkel and play some games with them. Tell the son to be a good boy and mama will come here fast.
as a guy with 3 younger sisters i can say that you must have patient and it will go away (or you lock them in the basement and walk away) just don't let him close to valuable stuff and you will be fine and make sure that the girl don't ion the crying because them you will be done and call your sister i did give my sisters a plush animal and they would quiet down fast
Usualy children cry from the 3 possible reasons: 1 ) rascals that want you to be their slave 2 ) hunger, thirst, poop, play with them 3 ) It's ALIENS i tell you !!!!
It's been 20 minutes and he's still crying. I'm honest surprised he hasn't vomited blood yet. He has quite the pair of lungs in him.
If drowning is not an option. Then food, cartoon, or walking outside with the kid might work. Just distract him.
