Whether your loved one is going into the hospital or coming home, it is a time when many details are in play simultaneously. And a time that you can become scattered and unsure of what to do. I remember being so lost and at times uncomfortable during those days and wish I had some idea of what to expect.
The list could be quite extensive depending on what your situation is, but here's a starting point that might help a bit:
For you in the hospital or care facility
Wear comfortable clothes and bring layers. The rooms can run warm for the benefit of your loved one, and though it may be 50* outside, it is often a bit warm inside.
Most facilities have a music channel on the TV with calming and peaceful images that can be soothing to your loved one and visitors alike.
Bring a backup charger for your phone or laptop, and perhaps a book/magazine, knitting…something to help keep you busy and your loved one doesn't feel like such a 'burden' if you stay for a while.
At the hospital, ask if you can spend the night. This may or may not be appropriate depending on the circumstances, but it made a big difference for my mom when my sister and I stayed with her.
Remember that your loved one is being cared for by professionals so you should not feel compelled to be there 24/7. It is far too draining, and you need your rest, too. You can always bring in a second set of eyes from family or friends if needed.
Bringing your loved one home
It is always a good idea to be prepared when your loved one returns with things they may need from the hospital or care facility: various medications, care devices - endless details to keep track of. The hospital will likely give you a list, but if they don't or you have questions - ask them for clarification. Do not be afraid to speak up.
Pick up a notebook/journal and make yourself a list to make this an easier way of keeping track. I can almost assure you that you won't remember those things you'll 'remember.'
These are starting points for you. Don't forget, in the middle of all this, your health, your rest, and your peace of mind are paramount.
Don't forget to B-R-E-A-T-H-E.
