Communication through the app
Started using one of those co-parenting communication apps like OurFamilyWizard and it's honestly a game changer. All messages are documented, there's a shared calendar, and honestly it takes the emotion out of things. My ex and I were arguing about stupid stuff constantly but since we started using the app everything is way more organized. Highly recommend if you're struggling with communication.
Glad you found something that works. Co-parenting is hard enough without the communication part making it worse. Those apps really do help take the stress out.
