I was the favorite child for caregiving not necessarily the favorite child. I was the dutiful eldest daughter who was always there. The other siblings were off the hook. I lived the closest and was a stay at home mom so I had more time to help with caregiving. My father had appreciation for all my hard work not so much from my mother. 

In my case it was not the favorite child. Far from it. I was chosen because my mother figured I was the most convenient for her. I have lived my life as the most responsible daughter and never gave my mother trouble. I was never her favorite daughter only the most reliable. I will always try to help my mother as best as I can, but at my covenience. My mother may have her favorites, but then so do I, my husband and 3 children equally. It is so sad to have to feel she is more of a unnecessary obligation than a mother I could lovingly care for. May god forgive me.

My parents put full blind trust in their only daughter who they though would care for them in old age.She dumped them soon after they became a burden to her life and I needed to take on the duties 100%.They both developed dementia and had numerous strokes but tried to convey their love and thanks for stepping up to the plate for them.Probably surprized them that the least likely came through for them.It surprized me too because I never imagined I had it in me.No regrets.Will love them forever.

They just pick the daughter. Of course I am also told that it's because I know how to do stuff and have - been trained? to be a supportive person.
