Pediatric chiro - for chill kids only?

How do you deal with toddlers who can't be convinced to stay still and relax, or those who are panicking and hysterical despite parents' effort to calm them down? I know chiropractic care is for all ages, but when it comes to kids under 3, can you still adjust them effectively if they can't/won't relax? As an adult patient, I'm asked to stay as relaxed as possible during the treatment, especially when we're doing the neck. Is it different for young kids? Thanks in advance.
