I had social services called for that exact reason. We were having huge problems with those neighbours anyway tbh.
A lovely lady from social services phoned me, saying she had some "information for me." Conversation went like this.
Her: We've had an anonymous phone call stating that your children are loud and screaming at all times day and night.
Me: Right, well I can tell you exactly who called you...
Her: (interrupting) I'm sure you can, to be honest.
Me: Yes we've had a lot of problems with them. My youngest does wake in the night, though not every night and we do our best to settle him quickly, especially as he shares a room with his sibling. And no, they don't certainly don't scream all day and night.
Her: I'm sure they don't.
There was a little after that but it's a bit personal but basically she was in no way concerned, had never been, had followed a couple of procedures and was just ringing me to let me know of the complaint, asked me for the phone number of my DD's preschool just to again confirm, and let me know there was absolutely no case.
Our neighbours would have been better off going to environmental health (not that it would have done much good considering our son wasn't waking nearly as often as they made out and we were dealing with it as effectively as we could).
So you don't have anything to worry about. Honestly. If someone was petty enough to call social services they would very quickly be able to identify you as not a risk.
