There is no strict threshold that a flat spot has to reach before a structural evaluation is worth pursuing. If a San Luis Obispo parent has noticed that their baby seems to prefer one head position, or that one side of the back of the skull is noticeably flatter than the other, a consultation with Dr. Bronstein at Beacon Clinic of Chiropractic is a reasonable step. The evaluation will either confirm a structural component worth addressing, or it will provide the reassurance that the pattern is mild and the baby's movement is varied enough that it is likely to resolve with basic repositioning guidance. Either outcome is useful.
The families who get the most from a plagiocephaly evaluation at Beacon Clinic in Grover Beach, California tend to come in earlier rather than later — before the baby has been in a fixed position for so long that the soft tissue and joint patterns have become well-established. That said, Dr. Bronstein sees infants across the full age range of concern, and the evaluation is equally thorough regardless of when the family comes in. What changes with timing is the conversation about what can realistically be expected and over what timeframe. San Luis Obispo parents who are uncertain about whether their baby's head shape warrants a visit are welcome to contact Beacon Clinic before scheduling to describe what they are seeing and ask whether it sounds like something worth evaluating.
