Lifting with family members

Pardon if this has been recently addressed but I'm new.

Anyone with strong opinions on lifting (eg. turns.transfers) with non staff. I know that sometimes family members, especially those who care for a patient at home, are better lifters. However, I'm concerned not only about following hospital protocol (and thus having any potential injury "sanctioned") but also about getting too casual about who helps me. So I rarely to never allow anyone to assist me who isn't an employee. Unless they've been trained by the PT dept for care of the patient at home. Plus, my rule means I don't have to make judgement on who might be or not be safe. It can cause some family members to become offended no matter how I try to explain that it has nothing to do with their abilities because I am not assessing their abilities.

Am I too paranoid? Anyone else have a standard of who they'll allow to help? And a way to gently insist to families?
