First AIBU so be gentle!
We have had on going problems with our neighbours, they use our drive without even mentioning it and things like that. It all came to a head a few months ago, the air was cleared and things have been better since then.
Last night my 2 year old woke up crying at 12pm, I went into him straight away as its unusual for him to wake in night now (we did have some issues with his sleep when he was much younger but I never left him to cry in his room). I settled him down, left him, all was fine, I popped to the loo and he started crying again. I went back in and resettled him, and could hear my neighbour mimicking his crying and calling our mummy.
Is this not a bit odd and and a tad unreasonable? To be honest I want to say something but don't think that will help!
