DH is working at sea so it's just me and DD 18 months at home. MIL arranged to take DD and her 2 other grandkids (4 and 7) to an adventure farm type place on Easter Saturday for an Easter Egg hunt event. There was also a petting zoo and face painting etc. I originally was going to go along with them but am 5 weeks pregnant and experiencing awful sickness. DD was bored with me unable to take her out so when MIL offered to take her anyway I said yes.
The adventure park is a 2 hours drive away. The reason she chose this and not somewhere nearer is because it is owned and run by her close friend. MIL doesn't drive and got the train. She picked up DD at 9 to catch the 9:30 train. I was told they'd be catching the 5:30 train back and DD would be back at 6. As soon as she picked DD up I went back to bed. Around 5 I get up and everything seems fine, MIO has sent pics etc. Expecting DD back in less than an hour I decide to make a start on our tea. Then about 5:45 I get a frantic text from MIL saying she'd missed the train. It was the last train of the day. She wasn't willing to ask a family member for help and claimed she didn't have any money for a taxi which I found somewhat odd. Despite feeling like shit I offered to go and pick them all up and she insisted she couldn't allow me to do that. I said it was fine etc, it didn't matter because it was my DD and she hung up.
She phones 10 minutes later and says her friend is coming to get her and they will stay the night at hers and come home first thing. I still insisted on getting DD but she said "No. Get some rest. Will have DD back by lunchtime tomorrow." I rang SIL and she seemed fine about what MIL waa doing. I couldn't pick my DD up as I didn't have the friends address. I went to bed thouroghly pissed off because I saw from the photos that DD's clothes got muddy at the farm and I hadn't packed enough nappies for an overnight.
She returns DD at 1pm (she said between 11-12) and acts like it's no big deal. I did make an offhand comment to her that I found it a bit uncomfortable that my toddled spent the night in a house with people I have never met and that I would've been happy to come and collect them all or pay some of the taxi fare for them so they could have come home that night. MIL has been quite funny about it and said she won't be so keen to take DD out in future. AIBU?
