Help with messages going to wrong phone

[2015Mustangturbo]

My parents both have iPhones. I switched the Apple ID to be different. When someone sends mom a message, text, Facebook or anything it goes to my dads phone. I do I fix this??!

Logging her into her own phone should do it =)

Be sure to change the Apple ID for iMessage and Facetime too. They should have separate Apple ID's. They could still share the same iTunes ID and share purchases. But iCloud, iMessage and Facetime ID's should be their own.
