No one can predict what will happen.
Generally the parent has superior rights over third parties about child custody. But your case is different-your son has been the primary custodian/caregiver/ for more than twenty months and this fact make your case different.

However, in a dispute between a parent and a third party, the third party has a greater burden, which is, that the proof that he or she is required to present must be clear and convincing that the children remain with her or him.

Some of those circumstances may be as follows
1. the children have been with the third party for a long time, or
2. the home of the natural parents for some reason is not fit, or
3. the parents themselves are not fit at the time that they wish the return of their children, or
4. the child is old enough, such as being a teenager, and does not wish to be with this or her parents
