I am so sorry that you are going through this, it sounds like you foster mother is breaking down the barrier/wall that most keep up. I know my foster mother never actually called Bug by his name- he was always bebe, nene, or a shorten version of his birht name, but never hsi full name. I never told them I was changing his name and then when he came home at 21.5 months, we made the switch.
Hopefully you and the foster mother can come to resolution on this so that there is the least amount of change for your son- perhaps you could present it to you foster mother like that- you are Momma, his name is XXXXX so that when he does come home, the transition is easier for him. Aks her what name she woudl like to be called by your son besides momma and then refer to her by that name/title so that she sees that you will continue with that title.

I am sending you hugs,
Love to you
