Ex-MIL usually only has contact with DS through his dad on his contact days. She called me earlier this week to ask if she could take him Christmas shopping on Tuesday and I said that was fine. It would just be her, her daughter and DS.
She picked him up and said she would be back by 6, all fine, then at 20 past 6 I got a call from her daughter saying they were on their way but stuck in awful traffic. They don't turn up til 8, DS is tired and hungry to the point of hysteria, and his dad, who doesn't finish work til 7 in the area they were shopping was there too.
I asked him how come he was there, and he said he has wanted to see DS so they hadn't left shopping til 7. Ex-MIL just did a silly face and said 'yeah sorry'.
Aibu to think this is not ok and not let her have him again on her own if this is how she acts? She knew he needed dinner, and it was past his bedtime. He'd hardly eaten all day with her (she made his bottle wrong...whole other issue) so he was a nightmare by the time he got home! And she and her daughter blatantly lied to me!!
