Sitting Development in Babies

Introduction

Sitting is an important motor skill that lets your baby explore the world from a new angle. It is gained gradually as head control and trunk strength develop. The timing can vary from baby to baby.

Signs Along the Way

Stronger head and neck control
Sitting with support
Balancing briefly by placing the hands in front
Gradually sitting without support

What Can Parents Do?

Support the trunk muscles with tummy time
Give your baby chances to practice on the floor, on a flat, safe play mat, with an adult right beside them
Stay close to prevent falls; don't surround your baby with pillows and leave them alone, and don't practice on a raised surface
Avoid keeping your baby in sitting devices for long periods; free movement matters

When Should You See a Doctor?

If head control is clearly delayed
If the muscles seem very floppy or very stiff
If your baby cannot sit without support by about nine months, or loses a skill they had already gained; for premature babies, corrected age is used

Summary

Sitting is a skill that develops at its own pace. A safe environment and chances for free movement help your baby move through this stage in a healthy way.
