Sometimes an incoming soul chooses to have two mothers: one biological mother who literally brings forth their physical body into the Earth dimension and one Spirit Mother who will raise, love and nurture the child. I call this a blessing of love because the soul group: birth mother, spirit mother and incoming soul have all agreed to support the incoming soul's creation and life on Earth to be a significant part of each other's Life.
When these situations arise the incoming soul needs a physical form to enter this realm. A woman becomes pregnant knowing she needs/wants to gift it to another family. The birth mother's soul agrees to gift the child to another family, and the spirit mother's soul agrees to love, nurture and raise the child that wasn't created by her biologically.
I believe that these children are extremely blessed because they had many souls love them so much that everyone involved agreed to be a significant part of each other's life, coming together to create the best Earthly life for the child and contribute to that soul's evolution. The two mother souls loved the incoming soul so much that everyone agreed to be a part of the conception and the physical delivery into the Earthly realm AND gifted the incoming soul with love and Life.
