Shared iCloud account problems
My husband and I have an iCloud account that we share, as I use very little of the Cloud. However, recently, all of the photos on his newer iPhone are now showing up on my iPhone. I do not have the storage he does, and I don't want his pics on my phone because I can't find my few pics among his MANY pics. Also, phone calls he makes are now showing up on my phone. This is a big problem for me too. What can we do to fix these problems but still share our iCloud space? Thank you!
iPhone 5s, iOS 11.2.1, other product: iPhone 6s iOS 10.3.2
