My younger sister has learning disabilities. She lives on her own, but needs round-the-clock care. My parents are trying to get a good care package in place for her, but at the moment, my mum is there a lot, including every night. Mum is exhausted.
Dad asked me a few weeks ago if DS (nearly five) and I would stay at my sister's one night a week, to give my mum a break. We happily agreed. We stay the night before a carer comes the next morning, to take my sister out for the day - so Mum can have up to 24 hours to herself. I get quality time with my sister, and DS is lovely with her - so supportive. He got her up and made her breakfast today.
Here's the problem: on her most recent night off, Dad asked Mum to take him to the pub (this happens frequently), and then to drive out again to fetch him later on - breaking up her evening, and preventing an early night. Mum's shit at saying no (and I partly understand why, because Dad does a good line in guilt-tripping - she's going for the 'easy' life). So she took him and collected him. And then the next morning, Mum turned up at my sister's before we'd left for the school run, because a contractor was coming to the flat and someone needed to be there (while my sister was out with a carer). Mum left Dad at home, having a lie-in.
Now, as much as I'm happy doing this favour for my mum, it is a bit tiring - I'm a lone parent. But I don't mind helping though, if Mum is truly getting a break; that would make it worth it. But really, she isn't getting that much of a break, because Dad makes demands of her when she's not looking after my sister.
Would I be being unreasonable to say to my dad, "We will continue to give Mum a break once a week if you fulfill your side of the bargain, which means sorting your own transport to and from the pub on these nights, and getting up the next morning if someone's required to be at the flat?"
