Okay you and your husband is on a date. You have a sitter and you are care free. Then an unexpected family memeber comes to the home but no heads up was given to the sitter so she doesn’t allow the cousin to gain access to the home. Cousin calls and wants to know why she can’t stop by and is upset you stand with the sitter.
It sounds like the cousin is going to have to move on. Yes the cousin called after coming but the issue is that the sitter doesn’t know them nor was alerted to their presence. The cousin should have called before she came to begin with. I know some family who likes to pop up and although it’s not my cup of tea to be okay with you get what you get when you pop up. The sitter is there to watch the kids. She shouldn’t have to be subjected to outside people in the home regardless of their relationship unless prior arrangements had been made.
I’m all for family but the cousin needs to accept that she came at an inappropriate time. To be mad and petty about it is just childish. She’s a cousin not a parent and even still people have to respect boundaries when coming to someone’s home. Give her a few days and she will be fine. I can’t see this being a blow up to the point where she no longer comes around.
I wouldn’t even bring it up unless she does. It’s your home and and she needs to respect your choices.
