Answer :
Most babies sit alone at 7 months old, with 50% to 90% achieving this between 5 and 9 months. The milestone of sitting unassisted is reached by 50-90% of children by 6 months of age. The correct option is A) 6 months.
The ability to sit independently is a significant developmental milestone for infants as it indicates progressing motor skills, which include both muscle strength and coordination. Based on average developmental progress, most babies sit alone at 7 months old. However, there is a range of normal development, where 50% to 90% of babies achieve this milestone between 5 and 9 months old.
Considering these statistics, a healthy child with the ability to sit up on their own, even with occasional tripoding, would typically fall within this age range, with the correct answer to the milestone achievement being Option A. 6 months. Monitoring these milestones is important because it helps identify if a child is on track with their motor development.
Delays in reaching milestones such as sitting up independently can signal the need for further evaluation by a pediatrician and potentially for early intervention services. Nonetheless, it's crucial for parents and caregivers to remember that each child develops at their unique pace within the normal developmental window. The correct option is A) 6 months.
