Baby kangaroos do not spend any time in their mother's stomach. They first spend time in her uterus, which is known as the gestation period, and then time in her pouch.
There are over sixty known species of kangaroo, ranging from the largest, the Red kangaroo, to the smallest, the Musky rat kangaroo. Therefore, gestation periods vary. It should also be noted that kangaroos have the ability to suspend the development of the embryo whilst another joey is still in the pouch, so they can be in a state of continuous pregnancy.
The musky rat kangaroo has a gestation period of 19 days, whilst the red kangaroo has a gestation period of about 33 days. Most other kangaroo species have a gestation period of 31-36 days. Most of the development of the joey occurs in the pouch rather than in the womb. Young musky rat kangaroo joeys spend about 21 weeks in the pouch, while red kangaroo joeys spend an average of 9 months in the pouch.
However, in reality, pregnancy length may differ. The mother kangaroo spends most of her adult life pregnant, but in drought times, she has the ability to indefinitely "freeze" the development of the young embryo until food sources are replenished. This is called embryonic diapause.
The same situation occurs for wallabies, also members of the kangaroo family. There are many different species of wallaby but, on average, they have a gestation period of 30 days and spend 8-9 months in the pouch.

How do marsupials feed their babies?
All mammals feed on mothers' milk when they are babies. Marsupials are a sub-group of mammals, so they also feed on mothers' milk. the other sub-group of mammals are the monotremes, or egg-laying mammals (platypuses and echidnas). Although they lay eggs, they are also classified as mammals because they feed their young on mothers' milk.
What type of animal gives birth to immature young that continue to develop within the mothers external pouch?
These are the marsupials.Baby marsupials are born extremely undeveloped, and are unable to survive at all outside the mother's body, until they can reach the pouch. They are born after a much shorter gestation period than a placental of equivalent size, and even the largest species of marsupial is only the size of a jellybean when it is born. After birth, it must climb up the outer fur of the mother and into the pouch where it attaches itself to a nipple. The teat swells in the joey's mouth, securing it in place so it cannot be accidentally dislodged. The joey will usually stay in the pouch for about 6-9 months, depending on the species, until it is developed enough to leave the pouch and move about independently.Marsupials include:some sixty species of kangaroo, including wallaroo, potoroo, pademelon, rufous rat-kangaroo and wallabykoalawombatpossum (Australia) and opossum (North America)gliderpotoroobandicoot, including the bilbyquokkaquollTasmanian Devilphascogaledunnartcuscusbettongnumbat (not a pouched marsupial, but a marsupial nonetheless)antechinusmarsupial mole
What is The Largest Marsupial?
The kangaroo is the largest of the marsupials, specifically, the Red kangaroo, Macropus rufus.A male red kangaroo can reach a height of 2.7m, or nearly seven feet tall, whilst the Eastern Grey kangaroo can reach 2.4m and the Western Grey 2.1m.
What animal can reach highest?
A kangaroo can reach the highest but maybe its a giraffe...i don't know.
How fast can baby kangaroos hop?
Baby kangaroos stay in their mother's push when they are born. At about seven to eight months age they are still in and out of their mother's pouch. When they are full grown they can reach speeds of up to 35 miles an hour. Kangaroos stay in groups so the babies must keep up with their mothers when they are out of the pouch.
Is the kangaroo a placental mammal?
No. kangaroos are marsupials. They are characterised by having a pouch in which they rear their young. Marsupial young are extremely small and undeveloped at birth. At birth, they take a long, arduous journey from the birth canal, driven purely by instinct, grabbing hold of the mother marsupial's fur which she has cleaned and made easier to traverse with saliva, to reach the pouch. Upon reaching the pouch, they latch onto a teat which swells in their mouth to prevent them from being accidentally dislodged during the mother's movements. There they stay for months, to complete their development.
How fast does the kangaroo jump?
The Red kangaroo, which is the largest and fastest of the kangaroos, can reach speeds of up to 70 km per hour, or 44 mph.
Is The mammal whose young mature in a pouch called a marsupial?
Yes. Marsupials are mammals with pouches in which they rear their young. Marsupial young are characterised by being extremely small and undeveloped at birth. At birth, they take a long, arduous journey from the birth canal, driven purely by instinct, grabbing hold of the mother marsupial's fur which she has cleaned and made easier to traverse with saliva, to reach the pouch. Upon reaching the pouch, they latch onto a teat which swells in their mouth to prevent them from being accidentally dislodged during the mother's movements. There they stay for months, to complete their development.Not all marsupials have pouches, e.g. the numbat has a mere flap of skin, but in animals where the pouch is absent, the young are still born undeveloped, and they cling by instinct to the underside of their mother's belly, still firmly attached to teats which swell in their mouths.

Marsupials give birth to immature live young that continue to develop within the mother's pouch?
Marsupials do give birth to immature live young that continue to develop within the mother's pouch. After it climbs up the mother's belly and gets in the pouch it grabs on to one of the teats. After several weeks, the young marsupial starts coming out more and more. It leaves the pouch when it is about 7 to 10 months old.
