Growth spurts. Do they really happen or are they just parent's observational bias?

In brief: Yes

During the newborn period baby grows ~ 10in the first yr and ~4in the 2nd & 3in/yr until puberty.
At that point they may jump up to ~5in/yr for a yr or so. Timing is different from kid to kid and in boys or girls. So in truth, growth both slows down & spurts as part of normal growth & development.
