However, the answer to the question may differ depending on who is asked. Most developmental therapists disagree with this answer and will tell parents that a baby develops other important skills by crawling on all fours, such as hand muscle development and equilibrium reactions to name a few. Human beings are bipedal. This means they use two leg s for walking. Before walking happens, an ytime between 6 and 11 months, babies typically crawl on their hands and knees. There are other ways babies may crawl, such as on their belly like an army crawl, or even with both knees off the flo or like a bear crawl!
The function of learning to crawl is for babies to explore their surroundings. When sitting up, a baby looks around and becomes interested in reaching distant objects and people. His or her world becomes larger in scope and moving from one place to another becomes important. Some babies use a previously learned skill such as rolling to move from place to place.
Any way that works for them to explore and satisfy their curiosity, they will do! Just days after birth, babies can push their legs and arms against a surface and move forward. They can also be put into water and their arms and legs move reciprocally, alternating as with crawling. A lot of growth and change takes place over the next six to ten months.
Skills such as rolling over, lifting the head and chest when on the tummy, and grabbing both feet while on the back, all happen during this time. All these movements strengthen muscles on both sides of the body, which enables a baby to develop the skill of sitting and reaching for a toy without losing their balance.
Vision is also developing from near sight to being able to see objects and people at a distance. Remember to always place your baby on their back while sleeping. If your baby enjoys tummy time continue to expose them through play to build up their tolerance and skill set. If your baby does not like his or her tummy, keep working on it in short periods of time and in different positions.
Try placing a towel under their arms to provide support so they can focus on lifting their heads or place them on your chest in a reclined position to eliminate gravity. This makes it easier for your baby to push through their arms and lift their head.
It is okay to use positioning devices at various times throughout the day, but the best place to develop strength and mobility is while playing on the floor.
This will provide exposure for the progression of their gross motor skills from rolling, to crawling and walking and it sets the foundation for fine motor skills and develops good core strength for speech. Also called contra-lateral, or cross-lateral crawling, this diagonal style of movement is vital in the development of an important pathway in the brain that belly crawling does not impact — the corpus callosum.
The corpus callosum is a band of nerve fibers between the hemispheres of the brain. Criss-cross crawling stimulates the corpus callosum to develop in a balanced way, facilitating the hemispheres of the brain to communicate. This helps support cognitive function, problem solving, and ease of learning. Crawling also serves as physiological stepping stone to walking. The crawling muscle actions start to reshape the hips, pulling them inward and forward. As the baby gets stronger she becomes better positioned to lift her body and balance for walking.
In criss-cross crawling a baby can also move a limb to the opposite side of the body, such as touching the right hand to the left shoulder. This type of movement is key for developing vision, hearing, learning, and integration of reflexes. You may notice your baby using other combinations of limbs and movements to move across the floor.
