Infant Developmental Milestones -- 6 to 9 Months
Between 6 and 9 months of age, babies will begin to achieve several new developmental milestones. Some milestones for 6- to 9-month-old infants may include sitting up unassisted, babbling using single-syllable sounds, passing a small object to you, and waving bye-bye. If your baby has not yet reached a particular milestone, remember that every infant develops at his or her own pace.
Infant Developmental Milestones for 6- to 9-Month-Old BabiesAs infants move into the second half of their first year, things start to get really fun. The developmental milestones that your baby will be passing now are even more complex and challenging. They are more aware of their environment and surroundings, and have reached a stage where they can actively explore instead of passively observe.
During this time, infants are also getting stronger and developing an even greater sense of balance. Their motor skills and coordination have both improved dramatically as well.
Specific Developmental Milestones for Your BabyAccording to the Denver Developmental Screening Test, the following skills are likely to emerge between 6 and 9 months. The developmental milestones that your baby will likely achieve during these fun, but busy, months are listed in the following sections in the most probable order of appearance for each category.
