Guys I'm going to the hospital for rehabilitation and need advice on what to do with my parrot

I am going to have rehabilitation in a Hospital 3h away from my home, i will be staying there for 3 weeks and then after few months i will be coming back for "follow up" (I don't know what to call it). The thing is i don't think that its a reason to give away my babys and i can't take them there so i am really scered that its gonna leave a mark in my parrots mental health and destroy our bond. I can't do anything but prepare them for it and i want to do my best but i still wonder if there is a better option. My parents will be staying with the parrots and i made them an entre Room so they will be able to fly freely.

What more can i do or should i do something else i really need yours Thoughts on this.
