Though they shouldn't be considered a strict schedule (all babies grow at slightly different paces), these markers can help serve as a guideline for pediatricians and parents to track a child's progress in four important developmental categories: social and emotional, language and communication, cognition, and gross and fine motor skills. Skills like responding to her name, rolling over in both directions and, later, crawling and walking are called developmental milestones, or actions most babies can complete by a certain age. What skills is your child developing at 7 months?
