Which of the oviparous presented feeds the young with milk?

Mammals are animals that feed their offspring with milk until they get stronger and can not eat solid food. Birds and reptiles lay eggs. Mammals do not lay eggs. But there is one exception – the platypus. They are the long-livers of our planet. Platypuses are mammals and they lay eggs at the same time. The female lays two eggs at a time. Sometimes it can be one or three eggs. The males prepare the nest, which they seal to protect the offspring from various predators.
