Hello!
If you are paired as an observer to your child's account, you should be able to view all the notifications your child gets in their canvas inbox in your observer account inbox as well. This however may vary by institution, school, or workplace so if you're not receiving notifications of your child's inbox, it's best to check and ensure you have the right settings enabled, and it also wouldn't be a bad idea to reach out to your organization's administrator.
But short answer: Yes.
Hope this helps, let me know if you have questions!
