is baby reindeer appropriate

Yes, "baby reindeer" is an appropriate term for a young or newborn reindeer. Reindeer are born in the spring and spend their first few months of life following their mother, learning how to walk and eat. They are usually weaned from their mother's milk at around six months of age and begin to feed on vegetation. Baby reindeer are typically playful and inquisitive, and they enjoy exploring their surroundings. As they get older, they develop their distinctive set of antlers, which can take up to three years to reach full size.
