Infant Siblings and no-risk comparison later-born infants were videotaped at home with a primary caregiver each month from 5 to 14months, with follow-up at 18months. As a group, Infant Siblings were delayed in the onset of early developmental milestones and spent significantly less time in a greater number of postures, suggestive of relative postural instability. In addition, they demonstrated attenuated patterns of change in rhythmic arm activity around the time of reduplicated babble onset; and they were highly likely to exhibit delayed language development at 18months.
