This. Parenting has gone downhill something awful this past 15-20 years, I have 2 children (now mid-20s) and they NEVER screamed and squealed, Nope, they really didn't. They giggled and played and had a good time in the garden in the nice weather - but they NEVER screamed and squealed. And there was never a single complaint about them. Yet this seems to be a thing now with some children, SCREAMING! And the parents let them do it. It's absolutely terrible parenting. 
Woman across the road from me has 3 children - aged 2 and a half, 4, and 6, and they scream incessantly some days. Some screams go on for a solid minute without the child taking a breath. And I have known a full 30 minutes of screaming from all the children, with hardly a break. Actually horrific. The 3 of them try to out-scream one another, and the mother is really brutish and coarse, and never speaks to the children properly. She just barks and shouts and snaps. So it's no surprise that the children are feral. She also does fuck-all about the screaming. I don't get it!
We are in the house opposite - some 125 feet away (around 40 yards,) including the 2 driveways and the road, and we can hear her kids screaming from our back garden, when they are inside the house with the windows closed! We can also hear them in their back garden - from inside our house with OUR windows closed. They are soooooo LOUD!
I pity their next door neighbours either side. One is joined on, one is not. The ones who are joined on live in the kitchen diner at the side, because the noise from the family is so unbearable (they are a couple in their early 60s, and one son aged 25.)
The other family - not joined on - can't go in their back garden now to relax/sunbathe/read etc, because of the noise from the 3 feral children, and often 4 other children - as the woman's 2 sisters bring their children around sometimes!
They are often in the garden from 7.30am to 9pm. (on and off mostly on!) Sometimes 3 children, sometimes 7, aged 2.5 to 8, screaming blue murder, bouncing up and down on the trampoline, splashing in the blow-up pool, playing on the bouncy castle, using the big plastic slide, and playing on the swings. Whilst SCREAMING 40-50% of the time they are out.
If they're not screaming, they're talking loudly, or shouting, OR the mum or one of the sisters is screaming or shouting. Awful family, badly behaved children, NO discipline. The mums never do anything with the children - just shove them in the garden, and no, it is NOT normal, or acceptable 'playing!'
I thank the Lord I don't live next door to them. I would have moved!
Anyone justifying this behaviour needs to give their head a wobble, and go on some kind of parenting course.
