Ear plugs sedatives sleeping pills any thing it sucks I feel ya but sometimes life throws you curves to test your strength

This is where you need to be assertive and confident, and actually get something done instead of suffering in beta-male silence. Walk over to the room. Knock on the door or if you see your roommate around, call them over. Just be short and to the point, "hey whats up?" in a friendly but confident tone. Compliment them on something, like their car, their clothes, whatever to flatter them but do it confidently not weird. Then just be like "hey look, btw, what's the situation with the person with the baby in your room?" And just say it casually. If you have been confident, ,talked slowly and chill-ly up to this point, your roommate (guy or girl, both) should apologize and laugh and be like "oh yeah im sorry about that, its bcuz of blah blah blah... this happened and they had to stay here.. blah blah" Anyway, listen to what they have to say and try to talk out the problem with them and find out if there's any other place the person can stay. If you REALLY have balls, you can always put your foot down and be like "look honestly that baby's killingggg me, its gotta go or hush up or something" but I wouldn't recommend going that far. Usually talking it out will lead to them offering some sort of solution ON THEIR OWN. Then once they do, high five them or pat them on the back and tell them its a great idea and that you'd really appreciate them doing that and helping you out, then invite them someplace cool that you and your friends are going or something (if applicable; if theyre around your age). In other words just be a boss and proactive and fix the issue. If worse comes to worse, get ear pllugs

I say drug the child. with Tylenol pm

just tell them, "listen, do you think you could be a little more quiet? it's not a huge deal, it's just I'm a day sleeper" I'm sure if you asked nicely they'd do something about it....

Ok there's a little bit of a double standard here. 1 got voted up for saying murder is an option and someone who flipped out about it got torn apart but this guy says shake them,gets downvoted and the people who get mad get thumbed up? Fml is a strange place.

If the little shit is old enough to speak understandable sentences the tell it to shut the **** up. If it's a baby, a little duct tape will keep it from screeching.

Hide about 15 alarm clocks around the house/apartment, all set for random times through out the night and see how they like it.

And you just sit in your room? Oh my gosh I would have exploded and kicked them out for a couple hours at least

I think it's fine time that you tell them to leave. You pay half the rent. You have that right.

Tell them to pay rent or get out. You live there too and have legal right to kick em out. Don't risk noise complaints for not your inconsiderate guest.
