2. DOLPHINS (AND KILLER WHALES)

Dolphin and killer-whale mothers make human child-rearing look simple. These sea creatures rarely sleep during their babies' first 30 days of life, because the newborns never sleep. These little swimmers have unlimited energy during their first month, meaning Mom has to try to keep up. (Brain Research Institute)

I have goats and it is not uncommon for a youngster to be asleep and fail to arouse when the herd moves off after I turn them loose from their pen (I typically make noise doing this and the herd is noisy in anticipation of being turned loose or getting fed). When it does wake up it begins bleating in a panic for its herd mates/nanny which are often out of sight. I have seen a goat up to about 6 mo. old do this. This is my experience.
