The story of how baby bats come into being is a strange one. Mating for northern hemisphere bats takes place during the summer months. But a delay in fertilization or in embryo development during hibernation means the babies don't get born until the following spring! Like human babies, baby bats (also known as pups) feed on milk.
Bat Babies. During spring, bats return from migration or awaken from hibernation and the females begin having baby bats called "pups". Bat pups are tiny when born, but grow up fast. Some species are flying and hunting on their own within a month of birth.
By the end of the bat maternity season, all of the pups born in the spring will be able to fly, and they will no longer be left in the roost at night while the mothers feed. Little Brown Bat (Myotis) Maternity Season: June 1 - August 15 Big Brown Bat Maternity Season: June 1 - August 15

Baby hares are born with fur. This is one difference between rabbits and hares. Unless the rabbit sick, or a mutant (seriously: I mean mutated genes), … then it will grow fur.
Bat carers have to ensure that the baby bats not only are well fed, but that they are nurtured and feel safe in their temporary new home. Providing affection to the bats is a necessity.

Between hibernation and baby season, the window to remove and exclude bats from a house is very narrow. Depending on weather, bats can only be removed after hibernation but before babies are born in late April through to May and once again when the babies have grown up but before they’ve gone back into hibernation in August and early September.
