Not sure of the exact right forum for this but I'm concerned and looking for input. I have an across the street neighbor who has 3 little ones 4 1/2, 2 1/2 and 6 months. Today when I know the oldest was at preschool I noticed her take a walk with her friend with no other kids in tow. I wouldn't normally jump to the conclusion that the kids were left by themselves but there was another instance where she came over to let her older two play with my kids and left the baby home alone by himself for 2 hours only going over to check on him twice, once after the first hour and then again after another hour. She didn't bring over a baby monitor nor is her house close enough she could have heard him crying if he had woken up. I thought at first maybe the two little ones where out with a babysitter because my neighbor took her walk and then came home and mowed the grass and still no kids in evidence but then I saw a friend bring home the oldest and suddenly she is in the backyard with all 3 kids, and the friend definitely only brought the oldest back from preschool. So either she has a nanny or babysitter at her house I don't know about, that also doesn't drive because there are no extra cars out there or she really is leaving these two little ones home all alone. Should I just continue keeping a close eye on her house to see if maybe there is a mystery babysitter that I haven't noticed or to try and see definitevely that she really is leaving these kids home alone? I don't want to make judgements about someone in error but I wouldn't be able to live with myself if she's leaving these kids home alone and something happens! WWYD?
