Proud Parent is a Gene Tonic in BioShock 2. It increases the amount of ADAM that adopted Little Sisters give the player upon finishing a gather, from 40 to 60. The final ADAM amount given upon putting the Little Sister in a vent, as well as the ADAM gathered during the Inner Persephone sequence, remains unchanged. If the player rescues four Little Sisters, a rescued Little Sister will leave this Tonic in a teddy bear at a nearby Gatherer's Garden.
