For example, newborn domestic cats cannot see, hear, maintain their own body temperature, or gag, and require external stimulation in order to defecate and urinate. [15] The giant panda is notably the largest placental mammal to have altricial, hairless young upon birth.

If placed on the mother's abdomen the baby gradually inches towards the breast, called the breast crawl [61] and begins to feed.

Thermoregulation is the ability of an organism to keep its body temperature within certain boundaries, even when the surrounding temperature is very different. A thermoconforming organism, by contrast, simply adopts the surrounding temperature as its own body temperature, thus avoiding the need for internal thermoregulation.
The term 'mesothermy' was originally coined [6] to advocate for an intermediate status of non-avian dinosaur thermoregulation, between endotherms and ectotherms. A more technical definition was provided by Grady et al , [ 7 ] who argued for dinosaur mesothermy on the basis of their intermediate growth rates , and the empirical relationship ...
Transient tachypnea of the newborn is a respiratory problem that can be seen in the newborn shortly after delivery. It is caused by retained fetal lung fluid due to impaired clearance mechanisms. [1] It is the most common cause of respiratory distress in term neonates.
