To be in tears over noisy next door neighbours?

[TinaTeaspoons]

The grandkids in particular are aged about 4 and 7 but screech and scream like toddlers when out in the garden. They are incapable of speaking in normal voices but then one of the aunts is gobby as anything too so the apple doesn't fall far from the tree. This can go on for hours and one of the kids usually ends up hurt which then results in loud crying. The aunts and uncles rile them up and encourage them to yell and scream. It's pretty much every Saturday and Sunday afternoon and all through the holidays. What's worse is that they have installed a hot tub right by our window which I can only imagine will make the situation a million times worse.
DH doesn't want to cause issues and will not say anything and will not let me. I cannot take anymore and think it's going to be a hellish spring and summer. Spent most of today cursing the noise and now in tears.

I also check the weather and prey for rain, last year was a nightmare and I'm already close to a full on nervous breakdown this year.
God knows how we'll sell the house when we can eventually afford it, we have a dispute to record (their kids screaming at 1am) and I know every other neighbour complained about their music (whilst we didn't I'm sure I'll have to disclose that too because I know of this issue).

Let's hope for a wet summer!!

Try using this out your window onto their knicker soup hot tub:

Loud Val Doonican on repeat . If they complain you have to have it that loud to hear it over their noise . People this selfish won't be changing anytime soon so make life uncomfortable for them too.
