heres a thought ... here in america its against the ethics rules, and breach of confidentiality if someone invited someone else to spend time with them while their client was asleep...like a therapist or care taker. usually what happens here in america is the care taker or other person acting in their professional role does not invite others over during work hours. they usually make plans for after work and in a place where it doesnt violate their clients rights to confidentiality.

my suggestion is maybe check with your boss first to make sure that inviting your friends and family over to a clients home or where ever the client is during nap times is not a violation of work ethics and confidentiality of the client.

then since you do understand the person you love does have other friends and family that they may want to spend time with them when you are at work you and your loved one can make an agreement that they will not come to your work, and make a schedule of when you and this person can get together... example maybe your plan can say something like every (name a day that you know you are free from work) so and so and you can do something together. that way you know already when you and this person will be getting together and your mind wont race with thoughts when you are working. because you already set a planned get together when you are not working.
