I HATE the way the hospital doesn't respect a child's need to sleep. While it isn't always feasible, I tell the night nurse that I would like to have EVERYTHING done at once, whatever time she sees fit, but once: vitals, IV meds, etc. Once between 10pm at 6am. And even at that I get up with a flashlight and help her do it quietly so that we don't wake my daughter. Almost all the nurses I've dealt with have been helpful once I've laid it out there. Of course this only works when they are in for a CF exacerbation, surgeries, etc., seem to have different rules, but I still try to get them to work with me.
As for staying up past bedtime, I try to start dimming the lights about 8ish. nurses work 7-7 shifts. So when the night nurse comes in to do vitals etc., its usually 8ish. AFter that visit, I dim the lights and we sit quietly.
I also have had to tell the RT that she will get her 4 therapies during waking hours 7am - 9pm only. They have left the vest machine for us in the room so that I can just give it to her before bed and don't have to wait for the RT who tends to show up late every time, usually after 10, but once she showed up at 1am!! WTH????
I am thankful that our docs let us go home with the IVs after just 4 days in patient. I'm always eager to get her home and on a more normal schedule.
