Most do not. These are typically R-selected species meaning that most of their energy is put into reproduction. More offspring for better chances of some surviving, and having multiple clutches per year. So how long they stay with the parents is typically zero. All are birthed from eggs, most with no parental watch over the eggs after they have been laid.
as long as they want to
No, frog parents don't stay with their eggs because the eggs are laid in water and frogs cant stay in the water for too long or they will drown.
as long as they need to.
It doesn't stay with it's mother. A "baby frog" is not a frog at all. Female frogs lay eggs that are later fertilized by male frogs. These eggs then "hatch" into tadpoles - the sexually-immature stage of frogs. The mother frogs will rarely meet their offspring.
