The main reason why a wallaby has a pouch on its abdomen is that, like all marsupials, the young are born very undeveloped after a gestation period that is much shorter than that of placental mammals of similar size. Upon birth, the joey must crawl to the mother's pouch where it attaches themselves to a teat. The teat swells in the joey's mouth, securing it in place so that it can continue its development within the safety of the pouch, much as a placental mammal protects its baby within its womb. The pouch is essential to the development of the young, functioning as the womb does in placental mammals.
The kangaroo's pouch is developed to carry around the baby kangaroo (called a 'joey') until it is large and strong enough to catch up to the mother or defend itself. There are many predators in the Australian outback that can easily prey on a young joey, and while adult kangaroos can defend themselves and jump away quickly from danger, joeys cannot. I have seen kangaroos in the wild and I can say that they often jump together in packs and are incredibly fast. A joey would be easily trampled if it was able to catch up.
It is only when the joey reaches at least 7-8 months old that the need to keep safe from predators is a consideration. Any joey dislodged from the pouch prior to this stands little chance of survival.
Essentially, the baby wallaby uses instinct. When a joey is born, its mother prepares a path for it from the birth canal to the pouch by licking her fur so it lies flat and in the direction the joey must travel. This is actually not to guide the joey so much as to stop it from drying out before it reaches the pouch. The tiny joey uses its claws and front legs to clutch the mother's fur until it reaches the pouch, where it attaches to a teat that then swells in its mouth. The joey stays attached there for a minimum of two months.
The name wallaby is believed to have originated from an Aboriginal Australian language, where it roughly translates to "small kangaroo." Wallabies are marsupials that are smaller than kangaroos and are native to Australia and nearby islands.
The pouch where almost all animals digest food is called the stomach. The stomach receives food from the esophagus and breaks it down using stomach acids and enzymes. The broken-down food is then passed on to the small intestine for further digestion and absorption of nutrients.
A baby wallaby, also known as a joey, typically weighs around 0.03-0.04 pounds (13-18 grams) at birth. The weight of the joey increases as it grows and develops while nursing in its mother's pouch.
There are dozens of species of wallaby. They each have different scientific names. Below are a few examples: Parma wallaby - Macropus Parma Red-Necked or Bennett's Wallaby - Macropus rufogriseus Yellow-footed Rock-wallaby - Petrogale xanthopus xanthopus Brush-tailed Rock-wallaby - Petrogale penicillata
The Toolache Wallaby is extinct, but fed on native grasses.

A small kangaroo type animal with a pouch is most likely a wallaby. Wallabies are smaller relatives of kangaroos and belong to the same family, Macropodidae, known for carrying their young in a pouch.

A wallaby joey stays in its mother's pouch for around six months, but may continue to suckle from the mother for up to another three months. It is usually independent by nine months old.
