Help!

Melissa

My 6 month old daughter will not sleep thru the night but all day all she does is cry unless someone holds her. We’re trying to break her of that so we just have to deal with her crying. So it’s literally been for the past week and a half crying and no sleep at night. I can’t let her scream all night because we live in an apt. I dont know what to do. Someone please help. I can’t do this much longer.
