Scared of family members

NA

Good day mamas. It's been a while here. I was wondering if anyone is facing similar situations and what helped. My boy is scared of his grandfather and uncle. His uncle doesn't leave with us so it's understandable but his grandfather lives with us. It started with him crying whenever he talked but now the moment he sees him he starts crying and will pull ny hand to go. Im not sure if this is a phase or what.
