🏊 Swimming is a natural, physiological, extenson pattern in babies that appears around 5 months, sometimes as early as 4, and should fade after reaching 6 months of age. Furthermore—it is a very important stage for the Baby.
💪 This pattern allows the Baby to achieve an upright position, as flexion positions previously dominated their development. In a way, it is a preparation for achieving an upright position in a few months—sitting, then standing and walking.
⚖️ Additionally, it is a natural balance and equilibrium training for the infant, as well as a protective support reaction, which will protect them from falling in the future. The Baby also practices shifting their center of gravity lower, toward the pelvis. So, every Baby goes through the swimming stage.
⚠️ But this pattern is the norm only when it does not dominate. When the Baby alternates between “swimming” and entering a support position, often initiating high support on straightened elbows. If, after 6 months or at the beginning of the 7th, you notice that this extension pattern is excessive—that the Baby is swimming constantly and rarely in support—you should promptly schedule an appointment with a physical therapist to evaluate potential muscle tone disorders and reflex integration issues.
🎬 I have 2 more parts of the Myth Buster series on this topic—about inhibiting extension pattern on the ball and how you might accidentally trigger it while carrying. We will publish both in the coming weeks!
