A situation like that would be stressful enough for the parents without the added stress of worrying about neighbours. I wouldn’t complain, but might buy myself earplugs.
THIS! This should be what neighbours should do.
Instead my neighbours would bang on the wall and swear and shout at us which just made the situation worse.
My DS didn't talk till he was 3. Between 18m and 2 1/2 he would wake in the night crying, and nothing we could do to keep him upstairs in bed and calm would work. I think he wanted to be near us, or a night terror had upset him, but he couldn't verbalise what was wrong. The first time they shouted abuse and banged was when he had croup and so was in a cycle of coughing in his sleep which would hurt him so he'd cry and cry until he fell asleep and so on.
I would be in tears trying to calm him down. We ended up taking him downstairs to watch tv and play with his toys. Just to keep him quiet so they wouldn't react. One of us would nap on the sofa whilst keeping an eye on him.
This then ended up with him wanting to go downstairs every night to play, but not understanding us when we tried to explain why he needed to stay in bed.
Their constant abuse made me fear my DS and his night wakings. I was in a constant state of high alert, I feared any noise that could wake him. For that year I did not like my DS.
In the last 18 months we have introduced a Gro clock, gave him a treat if he stayed in his room all night, slept in his room every night, eventually moved to only visiting him a few times a night, and now most nights he sleeps through. It's taken a lot of hard work, but I now don't fear my DS and enjoy spending time with him.
