My sympathies are with you ontheedge. When the missus and I first moved in together, the property (on east dulwich road) looked the part, newly done up, clean and bright. 3 weeks later the upstairs chaps got back from holiday and we soon realised the whole place had been done up on the cheap. That fake wood stuff had been laid everywhere and there was no underlay, in fact I'm not convinced there was any soundproofing between the floors at all. Every little footstep would actually cause ripples in a glass of water. Add 2 lively kids in to the mix and we almost cracked up. In fact we were so on edge the whole time that we almost broke up. It wasn't until we moved into a place with peace and quiet (and actually dark at night, the other place had blinds everywhere, and the other neighbours had a no curtains and a naked 1,000,0000 watt bulb that shone into our bedroom) that we realised we'd had no sleep in 5 months and had gone completely loopy. I've no idea what you can do, we never blamed the neighbours as what can you do, kids are kids really. We did mention it to their pops who was understanding, but again, what can you do? Best of luck and my heart goes out to you. Sorry I've not been more helpful.
