At seven months old, which skill should a child display?

At seven months old, a child typically develops the ability to sit without support, which is a significant milestone in their motor development. This skill indicates that the child's muscles and balance have strengthened enough to maintain an upright position while seated. Sitting independently allows children the opportunity to explore their environment more effectively, promoting further development in other skill areas such as reaching for toys or visual tracking.

While some children may show early signs of walking or standing on their tiptoes, these skills usually emerge later in the developmental timeline. Speaking simple words is also a skill that develops around the first year of life, making it less likely for a seven-month-old. Therefore, sitting without help is a more accurate reflection of the developmental stage for a child at seven months.
