The tenants upstairs chose to respond to my toddler's running around (on a wooden floor) during the day by banging on their floor whenever she did it. I explained, politely, there was no intentional disturbance, and that she is always in her cot by 7.30pm, but short of tying her up, there wasn't much I could do about the noise, but I would make sure she didn't wear shoes in the house etc. Also pointed out that the noise from their flat, stairs, door slamming etc, was probably worse in my flat than the noise from mine to theirs, given that they are above us. Am now being subjected to them deliberately stamping their feet outside my front door (it's a communal hallway) when they come in late from a night out, and the woman (the man seems the more 'reasonable' of the two) continuing to bang on the floor when DD makes a noise in the day when the man is out. This is the second night she's deliberately jumped up and down outside my door at 12.30-1am and, although DD and I will be moving in a couple of months, I don't need this kind of crap when I'm on my own with a 20-month-old. Am considering filing a harassment report with the local police just to get these ignorant tossers to see sense. AIBU?
