6 Month Old Baby Typical & Atypical Development Side by Side
Summary
TLDRThis video compares motor development in six-month-old babies, highlighting differences between typical and atypical development. It showcases eight positions to identify early motor delays, emphasizing the need to adjust for prematurity. The video illustrates how typically developing babies exhibit coordinated movements, anti-gravity control, and play, while atypical development is marked by limited reach, grasp, and stability. It serves as a guide for recognizing developmental delays.
Takeaways
- 👶 The video contrasts the motor development of a typically developing baby with an atypical one in eight different positions.
- 🪀 In the supine position, the typically developing baby can reach, grasp, and play with a toy, while the atypical baby struggles to do so.
- 💪 In the prone position with limbs extended, the typically developing baby can lift extremities against gravity, whereas the atypical baby shows little anti-gravity movement.
- 🌀 The typically developing baby has better trunk control and can roll independently, while the atypical baby's arms remain in a passive position, hindering rolling.
- 👀 In the side-lying position, the typically developing baby can visually follow and reach for a toy, but the atypical baby's neck and shoulder extension prevent forward movement.
- 🙇♂️ In the prone position with head and arms, the typically developing baby supports weight on extended arms and turns the head, while the atypical baby's elbows are behind the shoulders, limiting head and trunk lifting.
- 🤸♂️ The typically developing baby shows emerging upper extremity control and weight shifting, but the atypical baby lacks stability for upper extremity play.
- 🧗♂️ In the play position, the typically developing baby engages in varied play schemes, while the atypical baby struggles without stability to explore the environment.
- 🧍♂️ When pulled to a sitting position, the typically developing baby actively assists by flexing the neck forward, but the atypical baby has head lag and can only briefly hold the head up.
- 🧗 In the sitting position, the typically developing baby has stable head and trunk control with strong extension, while the atypical baby struggles to maintain an upright position even when supported.
- 🤸♀️ The typically developing baby can lean forward, reach, and right the trunk over the pelvis to sit upright, but the atypical baby requires chest support for stability and does not reach.
- 🧍♀️ In horizontal suspension, the typically developing baby shows full sustained extension, while the atypical baby can only briefly lift the head symmetrically.
- 🛡️ Protective extension is easily elicited in the typically developing baby, who brings arms forward, but the atypical baby does not extend arms to protect himself.
- 🚶♂️ The typically developing baby can turn the head freely and align the body in a vertical weight-bearing position, while the atypical baby lacks the necessary control for alignment and weight bearing.
Q & A
What is the main purpose of the video described in the transcript?
-The main purpose of the video is to demonstrate and compare the motor development of a typically developing baby with an atypical one in various positions to help recognize early motor delays.
How does the typically developing baby react when presented with a toy in the supine position?
-The typically developing baby reaches, grasps, transfers, and explores the toy in a well-coordinated motion.
What is the difference in the reaction to the toy between a typically developing baby and an atypical one in the supine position?
-The atypical baby is visually interested in the toy but unable to reach, grasp, or play with it as expected for their age.
How does the typically developing baby demonstrate anti-gravity movement in the prone position?
-The typically developing baby can symmetrically lift upper and lower extremities against gravity and bring hands to feet.
What is the main challenge for the atypical baby in the prone position?
-The atypical baby struggles to demonstrate anti-gravity movement, even with assistance, and briefly holds knees towards the chest.
How does the typically developing baby initiate rolling from a side-lying position?
-The typically developing baby visually follows the toy, reaches, and then rolls independently, initiating movement with lower extremities.
What is the main difference in the ability to roll between the typically and atypical developing babies?
-The atypical baby's arms rest in a passive wide abduction position with shoulder extension preventing rolling movement.
In the prone position, how does the typically developing baby support their weight on their arms?
-The typically developing baby is able to be on extended arms supporting weight while turning the head to follow a toy.
What is the main challenge for the atypical baby in the prone position regarding head and trunk lifting?
-The atypical baby has elbows behind the shoulders, making it difficult to use upper extremities to assist in head and trunk lifting.
How does the typically developing baby demonstrate upper extremity control and weight shifting?
-The typically developing baby shows emerging upper extremity control and weight shifting for reaching, grasping, and play.
What is the main challenge for the atypical baby in terms of upper extremity stability?
-The atypical baby has decreased upper extremity stability, preventing weight shifts towards the pelvis necessary for freedom of upper extremities.
How does the typically developing baby participate in play?
-The typically developing baby participates in varied play schemes such as banging, turning, mouthing, transferring, and shows a palmar grasp with increased digital participation.
What is the main difference in play between the typically and atypical developing babies in the prone position?
-The atypical baby is challenged in the prone position without adequate stability, unable to use vision or hands to explore the environment.
How does the typically developing baby assist in the pull-to-sit maneuver?
-The typically developing baby actively flexes the neck forward and lifts the head from the support surface to assist in the maneuver.
What is the main challenge for the atypical baby during the pull-to-sit maneuver?
-The atypical baby is minimally able to assist in the maneuver, with complete head lag until upright and only holds it up briefly in midline.
How does the typically developing baby maintain head and trunk control while sitting?
-The typically developing baby has stable head and trunk control with strong extension through the thoracic spine.
What is the main challenge for the atypical baby while maintaining an upright sitting posture?
-The atypical baby struggles to maintain head upright and in midline even when supported.
How does the typically developing baby demonstrate protective extension when tilting forward?
-The typically developing baby brings arms forward during this move to protect himself.
What is the main difference in the protective extension response between the typically and atypical developing babies?
-The atypical baby does not bring his upper extremities forward to the surface to protect himself.
How does the typically developing baby demonstrate weight-bearing on extended lower extremities?
-The typically developing baby demonstrates sustained weight-bearing on extended lower extremities.
What is the main challenge for the atypical baby regarding weight-bearing?
-The atypical baby does not initiate or sustain weight-bearing, making it impossible to develop control and standing.
