Text Message Forwarding - Child's Phone
How can I forward the messages from my child's phone to my iPhone for monitoring? I have set up an apple ID for them with family sharing. I've looked into the following settings to see if I can forward text messages from my child's phone to mine, but it doesn't appear possible.
"Settings > Messages > Send & Receive": only my child's iCloud account and phone number is listed here, I cannot add my phone number.
"Settings > Messages > Text Message Forwarding": This only lets me link their iPad, I cannot forward to my phone. There is no option to add any device manually.
