Who should tell the kids, mom or dad?
This shouldn’t be a job just for mom. Dad is going to be the go-to guy during mom’s recuperation from surgery, and during chemotherapy, if it’s needed. If mom is too overcome with emotion, Dad might do a solo act. But the ideal is to have both parents talking with the kids. And yes, they should use the word cancer (if you don’t someone else will) and the word breast (no matter how many giggles it elicits, that’s where the cancer is).
