My husband and I recently moved into what I suppose you would call a triplex apartment (we have neighbours who live upstairs and below). In the contract we signed, the landlord was very strict about no smoking and no dogs in the building, which is perfect since we're nonsmokers and we have a 2.5 year old son. The first day we moved in, the entrance smelled strongly of cigarette smoke which I was disappointed about since one of the reasons we chose this particular building was it's no smoking policy. We weren't sure which neighbour it was, so we messaged the landlord who immediately got back to us and said he would contact the tenants to remind them not to smoke. Afterwards, the downstairs neighbour approached my husband (she lives with her boyfriend and two kids, around 9/10 years old), and apologised for having smoked inside. She said she usually smokes on the balcony, but she was drunk celebrating the New Year. We said no problem, but then a few weeks later the entrance smelled of smoke again. It was a really cold day, so we guessed she just didn't want to go out on her balcony to smoke. Even still, my son's health is really important to me, and since the landlord was coming to visit us about another issue, my husband once again mentioned it to him. Again, he reminded the neighbours not to smoke. Since then, the woman neighbour doesn't smile or return our greetings, so I'm guessing she's pissed we 'snitched' on her. Not long after, they got a dog which is also against the building rules. The dog occasionally barks and whines, and has almost woken DS up from his naps during the weekend, and it also barks at us when we're getting into our car and it's tethered on a leash outside. My son is well behaved for a toddler and rarely throws tantrums, and if he does we deal with it pretty quickly. However, he is an early riser, and he is usually up between 5-6am most mornings. When he wakes up, I try and keep him occupied in his room with his toys and whatnot and stop him from making too much noise until it's time to get dressed and have breakfast, but he's still an active toddler, and sometimes he'll drop a toy on the floor, or run around. On two occasions now, the neighbour below has banged on her ceiling when my son was being 'too noisy.' It happened again this morning when he ran from his room to the kitchen (he wasn't wearing shoes, he was still in his pjs), and it was 6:20. It's half-term here so the neighbour's kids will be off school and I guess the neighbour was still in bed, but my toddler doesn't know that! It really pissed my husband off that she knocked, so he knocked back. I'm not a confrontational person and I was hoping to have good relations with our neighbours. I also thought she would be more understanding having two kids of her own. Like, how quiet were her kids when they were toddlers? Has anyone been in a similar situation and do you think she's overreacting? I now dread the early mornings and I panic every time DS makes a noise, thinking the neighbour is going to make a complaint. If she does, then I'll be tempted to tell the landlord about their pet dog!
