what does the little boy want to do? If it were me I would take him and like others have said explain to him what is happening. Think too about his future in that when he talks about her and asked if he went or not you will have to tell him he didn't go. I think he might would be upset. When my mom died my brother had little ones. He talked to the hospice nurse about it and she advised to never keep children shielded from a death.
