Alexiah, I was a nurse for special needs children in their homes. When I took on a new case, the family shared with me upfront that the deceased Grandfather of the child comes to visit him every day. I have had similar experiences in my life, so I didn’t hesitate taking the case.I would see this 18 month old look towards the door, get all excited and say “Grandpa”. The child would keep playing and after a while, the child would wave and say “bye, bye Grandpa”.
I took care of another child that was limp and couldn’t talk. During the day she would all of a sudden look to one of the corners of her room and start laughing. Her Mother told me she believed she was seeing angels.
I hope you find comfort that Jesus, his Grandfather may be very well watching over your son.
