What age range do infants show protective extension laterally?

Infants demonstrate protective extension laterally typically around the age of 8 to 9 months. This developmental milestone is an essential aspect of motor development, as it indicates the growing ability of infants to respond to potential falls or hazards.

At this age, infants begin to have better control over their balance and coordination. When they are seated and sense that they may tip over to the side, they instinctively extend their arm out to the side to prevent falling. This reflex not only reflects their increased strength and muscle coordination but also their understanding of spatial awareness and the need to maintain balance.

Recognizing this age range reflects an awareness of typical developmental progressions in infants, which is crucial for caregivers and educators. Understanding these milestones helps in monitoring infant growth and providing appropriate supportive environments to encourage further motor skill development.
