about 4 to 8 babies a month because it takes 6 week to have babies
actually it takes 21 days for a mouse to have babies and the litter size can range anywhere from 2 to 12 babies a litter so if the litter ranges in 8 babies a litter you could have 139 babies a year
It depends on the type of Mammal. A human will usually have one or sometimes two babies per year but they can also have more than that.
Mammals like mice and guinea pigs can have lots and lots of babies.
Most mammals do not lay eggs. Only monotremes, which are specifically egg-laying mammals, lay eggs. There are two types of monotremes: they are the platypus and the echidna.
The platypus lays between one and the eggs once a year, during the breeding season. Echidnas lay a single egg each annual breeding season.
Depends on the Mammal like Elephants generally only have one baby, but mammals like mice, cats or pigs for example can have multiple births
Small mammals will often give birth to over 50 babies annually. Larger mammals have a much lower birth rate of 1 or 2 per year.
