    A fascinating new study from Poland is shining light on a growing developmental concern known as "verticalization"—the practice of putting babies in upright positions too soon or for too long. Think of baby jumpers, walkers, seats that hold infants upright before they're ready, or extended time in car seats.

    What the Research Shows

    The study highlights that premature weight-bearing can interfere with natural crawling and developmental milestones, place excessive stress on an immature spine, alter proper neurological development patterns, and lead to postural imbalances that may persist into childhood.

    A Chiropractic Perspective

    At Slak Chiropractic, Dr. Linda Slak—a board-certified pediatric chiropractor and ICPA instructor—has extensive experience evaluating infant development. Her neurologically-oriented approach helps identify and address developmental concerns early.

    What Parents Can Do

    • Allow plenty of supervised tummy time
    • Let babies develop crawling naturally before standing
    • Limit time in restrictive devices like jumpers and walkers
    • Consider pediatric chiropractic assessment if you notice developmental delays
