💫 Midline Crossing - 6mth to 4yrs 💫
Babies start to cross their midline to play with their feet at around 5 to 6 months. From around 6 to 8 months of age they will cross their midline to reach for an object intentionally. Crossing the midline is a very important developmental skill, which continues to increase and becomes much more refined around the age of 4 years.
The midline refers to an imaginary line down the centre of the body that seperates the body into a left and right side. By encouraging a baby to cross their midline, messages are being sent between either side of the brain, which in turn encourages communication between either sides of the brain, supporting coordination of both sides of their body (bilateral integration/coordination) for a multitude of two-handed tasks, as well as much later down the line for reading and copying work from a board (which requires this skill!). It is essential for brain development!
When we perform activities that cross the midline of our body, neural pathways are built in the brain that are integral to gross and fine motor tasks as well as cognitive skills. This supports our little ones in their everyday actiivities and well into adulthood.
You can start slowly with tummy time, you don’t have to leave your baby to it - it’s an opportunity for interactive, connected play.
You can do something as simple as having your baby lay on their tummy, and encouraging them to reach for toys on the right with their left hand, and then the other way around.
Crossing the midline play activities can be done in any position for play and will benefit your baby or child’s brain development.
If you would like more information on age appropriate crossing midline activities from 6mths to 4yrs to use at home and in the classroom, please do get in touch.
There can be many reasons why a little one may be struggling with this activity and further assessment may be required by a Paediatric Physio. If you have any concerns regarding your little one's development, please get in touch!
