There is no definitive answer to this question, as the number of babies a guinea pig has can vary depending on a number of factors, including the breed, the age of the mother, and the health of the mother and father. However, some breeds of guinea pigs are generally known to have smaller litter sizes than others, including:
* Teddy guinea pigs typically have litters of 1-2 babies.
* Sheltie guinea pigs typically have litters of 2-3 babies.
* Coronet guinea pigs typically have litters of 2-4 babies.
It's important to note that these are just general averages, and the number of babies a guinea pig has can vary even within the same breed.
