Over easy or sunny-side up? Mom feeds her eggs to baby. Her eggs.
Poison dart frogs will breed throughout the rainy season. The males attempt to attract females by perching on a leaf and giving a trilling, buzzing call. Once the male has attracted his mate, together they will search for a location to lay the eggs. The female lays her eggs on the surface of a leaf while the male follows behind her and deposits his sperm. Females may lay anywhere from 4 to 20 eggs (National Aquarium in Baltimore, 1999). Once the eggs are fertilized, the female will stay by her eggs to guard them. After about ten days, the tadpoles break free from the jelly-like egg mass and use their tails to swim onto the mother's back. The female will transfer the tadpoles one at a time to pockets of water, usually in the axils of bromeliads (air plants). D. histrionicus is unique in how the tadpoles feed. D. histrionicus are obligate egg feeders, meaning to insure proper development, the tadpole must eat infertile eggs from its mother (Zamora et al 1999). The female will return to the bromeliads every other day and deposit these infertile eggs into the water. The tadpoles need three months to complete metamorphosis. Once metamorphosis is complete, the juvenile frog will climb out of the bromeliad and begin terrestrial life on its own.

It's kinda like picking someone else's nose and eating it. Right? Right?

Those froggies have brains the size of a grain of millet. How does the mommy frog remember to feed the kids?! The world is a strange and beautiful place.
