I can relate somewhat to those feelings. Before my mother died she went to live with my oldest sister which we all agreed was the best place. My mother attached her emotions to my sister and didn't trust anyone else with her care. One weekend I brought her to my home so sis could go on a mini vacation and I ended up taking mom back to sis's house.

After my mom died I was grateful that she felt safe in my sis's house but yet on the other side I was upset that my mom didn't trust me enough to take care of her.

So I had mix emotions of how I was feeling and how I didn't want to feel that way....but still I was....EMOTIONS......gosh......

I think you are doing the right thing in not flying so much. Unfortunately you can not do much for your father but you can for baby who has a long life ahead of them.
