Don’t know what to do about my new neighbours...

So about a month ago I had to move out of where I was living due to my roommate putting my life in danger. I moved in the middle of the term (I’m a medical student by the way) which was insanely stressful, but I survived it. I managed to find a nice apartment that was too expensive and it’s advertised as being a quiet building. Previous med students from my university have lived here as do a number of other professional college students. I had to sign a noise contract upon moving in as well. Which is great because the little time I spend at home I spend it sleeping or cramming for the next days cases (I’m in my practical years).

I had a new neighbour move in recently. They’re above me so I expected a little noise from chairs, walking, etc. But, they have small kids that are up all hours. They run around the apartment and my furniture will shake (all of which is solid wood by the way). They scream too. I understand that kids are kids, but I grew up with 3 younger siblings and we never made this kind of noise. Especially at 3am (yes these kids are running around like shrieking elephants at 3am). I’ve had such a hard time sleeping and it’s starting to really affect me considering I don’t sleep already. It was so bad tonight that I ended up driving back to the hospital to sleep in an on-call room (which is not comfortable by the way) for 4 hours before my next shift started. I’m exhausted.

I tried asking the mother yesterday if she could have her kids be more quiet after 10pm (quiet hours start at 8pm in our building). She told me to get lost and that I needed to move out if I couldn’t handle a little noise. I can handle a little noise, but my furniture shouldn’t vibrate and I shouldn’t be able to hear her kids at all hours. The guy who lives next to me can also hear them, though it’s not too bad for him, but he also spoke to the parents and got the same response.

They are defiantly in violation of the noise contracts we all have to sign to move in, but I feel so awful about reporting the family. They just moved in and I don’t want to be someone the pushes others out (I mean I just went through that awful process myself). But, I can’t handle this and I defiantly cant afford to break my lease and move again.
