A childhood belief about prayers

This happened to me when I was a child of about 4 or 5 years of age:
My mother used to pray with me every evening before I had to sleep. Eventually she abandonded this habit but told me, that it would be very important to pray independently, e.g. for my brother, sister, grandparents etc., because god would be allmighty and could see and do everything.

Firstly I prayed every evening, because I believed in what my mother told me. But by and by I grew weary of this and so one day I prayed: "God, if you are really allmighty and if you really can do everything, could you please,please pray for me every evening ! "
After doing this I breathed a sigh of relief, because I felt freed of my duty. Honestly, I never told her...
