1. It’s better to have cohesion between parents. That may mean one parent talking to the other before talking to the nanny, or nanny always talks to just one and into is relayed.
I’m doing this. One parent is paying me for the whole year, including when kids are with the other parent. So, all communication goes through the paying parent.
2. Something happened. She could have witnessed something, with or without your child. She could have had an argument, he may have made a pass or she could have been demeaned unintentionally. Without asking you won’t know.
My DB is casually demeaning, without realizing. He’s just clueless that stating that x will take care of kids on their day off, and never asking if they’re available or asking how much it would cost is very entitled and inappropriate.
