Kids spend a lot of time sitting at their desks, so maintaining good posture is vital for spinal health.
Teach them to sit with their shoulders relaxed back and down, with their chair tucked in and both feet firmly on the floor. If you see them hunching down over their desk, gently encourage them to sit up straight. However, please note if they keep putting their head down close to the desk it may be worth having their eyes tested.
Please remember to model good postural habits yourself, especially if you are working from home. Spinal health is important at every age!
