So
dd, who is 7, went for a weekend away at the seaside with her father, stepmother and older half sister.
dd sees father and step mother weekly, sees older half sister maybe once or twice a month. She hasnt spent more than one or two nights with father for several years.
dd got back today and by all accounts had a lovely time. However she mentioned that stepmothers parents joined them for a day and father, stepmother and stepmothers parents went into the local town and left dd and her 12 year old half sister in the caravan by themselves. dd isnt sure how long they were away for but said it was "ages" and also said that her half sister had to make her lunch as she was hungry and the adults hadn't come back.
im really unhappy that dd was left in the charge of a 12 year old who sees her maybe twice a month and was left for a length of time where the 12 year old had to make her a meal. i would maybe be less upset if the adults had run to a local shop or something along these lines but it was clearly longer than that.
Im about to phone the ex and tell him that its totally not okay to leave dd but just wanted to gauge opinion on if im BU???
