How do I complain about a screaming baby?

I live in a block of apartments and my very noisy neighbours now have a baby that wakes me up every morning. I work shift work so I need to be sleeping.

They were noisy before the baby because they also have a barking dog, but this just makes it 10 times worse. Walls are not double bricked so I can hear everything and vice versa, however I am super quiet.

I know babies cry and obviously they can’t help it if the baby won’t shut up, but how do I confront them without sounding rude about it?

Thanks for all the negative comments you guys are the best 😘

can I add the parents we’re getting high until 1am last night?
