Not necessarily. The Indian black buck (a type of antelope) does not
have any scent for the first few days of birth. It's not until the
fawn (the correct term?) is a few days old and somewhat mobile that
its scent glands kick in. Until then it is hidden off in long grass
somewhere away from the main herd where it spends much of its time
alone just lying still, with the mother coming in to feed it
occasionally.
        If tyrannosaurs had such good senses of smell then perhaps
some dino babies also used this technique. After all, the black
buck's main predator is probably the tiger, the largest extant
terrestrial carnivore (some bears are bigger, but mostly herbivorous /
insectivorous).
