24/7 till baby’s home

Me and my girlfriend have been in the NICU with our son for about a week now and have stayed here on a couch in the room. The longer we stay I’ve started to realize how uncommon it is and I’ve grown to feel uncomfortable kinda like me and my girlfriend are overstaying our welcome. I turned to Reddit and seen people talking about having schedules of coming 4-8 hours a day. I guess what I’m asking is it weird to the nurses that we haven’t left yet? They have tried to give us gas cards almost making us feel like they want us to leave. Also comments from nurses about how long we’ve been here.
