New Neighbours Banging on the Wall every day!

[Timescape2003]

We live in a 3 bed semi and have two boys 12 and 10. Our 10 year old has ADHD and is on the Autism spectrum. 6 Months ago a young couple moved in next door, both have 9-5 jobs, she is very polite he likes to smoke weed and is swears a lot on his phone in the garden.
Every day without fail he will bang 3 times on the wall if hears anything.
I spoke to him and explained that we have kids and they play but we keep the noise down as much as possible, he seemed very understanding and could wait to get in his car and go, he didn't want to discuss it. This morning eating breakfast, he could here us talking so banged on the wall at 7.15am. My Wife is feeling harassed and stressed by the daily banging, so this time I went upstairs and slammed the wardrobe doors a dozen times to see if he likes banging...bad of me i know , but its stressing us all out and my son with Autism freaks out when he hears the banging..any ideas?

God he’d be forever banging on the wall if he could hear my neighbours, and they’re just going about their daily business! I can hear them now, talking. Can hear then on the stairs and heard the Mrs in the phone the other week “oh my god, oh my god!!”. I’d be inclined to knock back though, you can’t live your life in silence based on 3 knocks. But also if your banging your wardrobe doors, does this not stress your child also?

I'd speak to/text them to say it seems like DH bangs on the wall three times whenever he hears a noise here. Unfortunately, as you explained when you spoke, we have children aged 12 and 10 and (as much as we teach them to be considerate) that comes with a certain amount of noise. The younger one has ADHD and suspected autism and finds the banging very upsetting. If you have any concerns about the noise we make, please come by and chat rather than bang on the wall, we think it'd be better all round for neighbourly relations ;)

My neighbour has a son with autism and he is always screaming and banging, it really pissed me off until my neighbour popped round to ask if we hear the noise and to let us no he has autism and since then i clearly dont mind about the noise so hopefully your neighbour will be the same

I think its worth trying to talk to them again maybe this time to the lady as she seems more friendly. When I banged the wardrobe doors I did it with my son and told him its just a game if they bang we will bang back, this seem to cheer him up.
