Our next door neighbours have a toddler, and he's seriously cute to look at but he's been having daily (often several times a day) tantrums when they put him to bed. I know kids go through difficult periods and I know from experience with relatives/friends kids that they can be noisy. But this has been happening every day now for four months. In the evenings when they put him to bed he can sometimes manage to scream and yell for up to two hours, and even when he finally exhausts himself and sleeps he'll wake up around 2/3 am and have another little session.
My bedroom is on the other side of the wall from his, and he's honestly so loud that even through earplugs he's often woke me up in the middle of the night with the noise. As I type he's been screaming "daddy, mummy" for 30 mins non stop.
I live with some friends and we're all young professionals but we never have noisy late parties or blast music at people because we all enjoy a quieter lifestyle. I don't want to be the unsympathetic neighbour, but the noise he makes is starting to really get to us all, and its been incessant for months now. I'd like to think they're doing all they can but I really don't believe they are. Leaving him to scream for hours on end clearly isnt working.
Would I be unreasonable to go speak to them about it? How would I even broach the subject? The only contact they ever made with us was to ask if we'd keep an eye on the house for the week it was empty before they moved in, and since then nothing. I dont want them to get defensive, but it is unfair that we're all suffering his tantrums as well.
