He needs some care with cleaning, sheets changed and some meal prep. Transporting to medical appointments. He’s in a wheel chair but can transfer form chair to bed with support. Or chair to car. Transfer to chair in shower. I live in Lakewood Colorado
Don't see why you would need anything, if your just caregiving.
Best of luck
Are you not just a family member/friend helping someone?
Are you expecting payment for your help?
If so that's something to discuss with ex hubby or your son.
