DD recently started reception and only 3 children from same pre school are in same primary school. One being my neighbours daughter. No idea what I or my daughter are meant to have done but she has been blanking me and upset my daughter on one occasion as also ignores her, and keeps her daughter from talking to mine?!! It's making me feel really insecure and anxious at every drop off and pick up. Trying to avoid by getting there early, and when I do see her I always say hello, morning or whatever and smile but get absolutely nothing back and feel I look an idiot to anyone watching as she literally blanks me! We have never been best friends or anything but always chatted on way to/from pre school, in the street etc. Was going to invite her daughter and a couple of others round for tea one day after school this week to try and smooth things over, although assume she will say yes and make last minute excuse, or just say no. How will I know if she's genuinely got plans or just doesn't want to come? I don't want to cause even more friction or even an argument by out right asking what the hell her problem is, but this is affecting me so much I'm considering moving house and or changing schools. Although this is the school I wanted for my daughter, but if this continues its only a matter of time before she upsets my DD again. WWYD? My DH is going to knock on their door and personally invite their daughter to tea to avoid any misunderstanding over messages with no tone of voice. As far as I know from the teacher the girls are playing nicely together at school and are good friends.
