I just opened a page to ask for some advice. So I moved into a new property 2 months ago. My daughter has made friends with the 4 children that live next door. So to begin with everything was great but slowly I have started to notice things and it's worrying me. Firstly the children are out playing in the corridors of our apartments until 10/10.30pm long after my daughter and everyone else has gone to bed. Secondly they go to the same school as my daughter and one day 2 weeks ago she rang me asking me could I collect her children as she was running late. My fiance is a stay at home parent while I work so he does all the school runs etc so I called him and he said no problem. When he got to the scho it turns out her 4 children were there. She hadn't collected her youngest at collection time she left her to come home with the others sitting in the school for an hour waiting. The schooldid not seem happy about it and my partner was not happy at all as he had to drive home with 4 children in the back and he was fuming. On getting back the eldest child ran down to our local shops he is allowed by his parents and came back with loads of sweets. My partner wondered where he had gotten the money from he said he found it. My partner was suspicious and went down to his car to check and the eldest boy had taken all of the money from my partners car just small change but took it none the less. My partner very calmly told him he knew he had taken the money and the boy confessed to it. His parents then arrived home 4 hours later. We feed these children and let them play in our home but I have put a stop to that as I cannot trust them now. Then last week there was really loud banging on the door and when I opened it the kids were all shouting that their little sister had been kidnapped. After alot of worrying and running around trying to find out what had happened their dad casually strolled onto the corridor and explained to me that he had brought his youngest (4) to the library and forgotten her. And that his wife was gone to collect her 😲. I was so shocked. But then Saturday night just gone more banging on my door. I opened it and its the kids from next door. The little one had a tooth ache and they asked me how could they fix it. This was 11pm. I asked where are your parents. They told me gone to a party. I said when will they be home and they said 12pm so I asked who was minding them and they said the eldest. He is 10years old. Minding his 3 younger sisters. I sent them onto their apartment and told them to lock the door do not open it for anybody and do not use any electronics gas etc. I didn't know at this stage if they were alone but I stayed up all night listening out for them and low and behold their parents stroll in at 5am. They had been alone. I really don't know what way to approach this. My daughter told me yesterday they are moving back to Romania their home country next year. Any advice would be great thank you.
