As I can't take it anymore, it has been going on every night since July and I am at my wits end. The mum moved out around Easter time and left the dad with the kids and I think it is all a bit much for him as they have turned into the neighbours from hell. I would speak to the dad but he is literally never home hence why we have the issue of loud music until gone 2am nearly every single night. It is disturbing us, youngest dd just started reception and has been so tired from being woken up constantly she has fallen asleep in class, dd2 who is in 6 is not fairing much better and well me and dh are knackered absolutely knackered. I have tried ear plugs for the kids but they don't seem to get on with them and actually why should my 4yr and 6yr old have to wear ear plugs every night? I have tried them myself they do dim the noise to a more bearable level but do absolutely nothing for the vibrating wall and floor. We can't move bedrooms around as our house is sideways onto theirs so all 3 bedrooms are on the wall adjoining the houses where the sons bedroom is, our garden is at the side of our house not the back but still runs parallel with their garden. I know he has been late for school not going to school as on these days the music starts around mid day instead of 3pm and carries on until early hours. So WIBU to when I see him coming home from school next to ask him/tell him politely to turn his music and bass down. I haven't knocked the door late at night as he is still a kid and home alone so fells wrong. Part of me thinks I should tell him but on the other hand I would hate for a neighbour to do this to my dd's for I don't know say being a bit loud/silly on the trampoline Or something. So mumsnet what the fuck should I do?
