Divorce finalized March 2022, 50/50 parenting plan with equal decision making including non emergent medical decisions. Ex has gone anti Vax and is now against getting the kids vaccinated against covid and I feel it's important. This is against how we parented while together, we always vaccinated the kids anytime the was a shot they were due for. I have tried to discuss it with her, even stating I will follow a Dr's recommendation even if that means they don't get it. She will not. Is mediation the only way around this? It seems pretty messed up that she can get her way by default or inaction on this.
