As your child climbs the stairs they’re using all of their body and senses. They are developing strength, control and coordination in all of their body parts including the large muscles in their trunk. Having a strong core, or trunk, is important as it helps children with good sitting posture. Good sitting posture is important for developing writing skills.
Encouraging your child to move and climb in different ways helps them to understand that they can use and move their bodies in many ways. As they explore the different ways their bodies move they are learning about measurement, space and size and how to move within and around objects.
Using language to compare and describe helps children to understand that there are different terms and tools we use to describe measurement. Measurement helps us to understand size and to successfully navigate around the environment. As children develop an understanding of size they begin to explore their space and to experiment with the variety of ways they can move their bodies and objects into, around and through space.
