Development & Milestones for Infants (Birth - 12 months)
Development & Milestones for Infants (Birth - 12 months)
Your Baby's First Year
Your baby’s first year is one full of developmental milestones. These are skills like rolling over, sitting up and first steps. It’s also things like smiling, cooing and waving “bye-bye.” Each of these milestones are things most children do by a certain age. They cover a wide range of behaviors like playing, learning, speaking, and moving (from crawling to walking to jumping).
80% of Your Child's Brain Develops by Age Three
It’s during this first year that your baby’s brain begins to develop memory, language, thinking and reasoning skills. They learn by reaching out and exploring their world. They listen to you and begin to understand what names you use for people and things. They also learn love and trust from the way you cuddle, hold and play with them.
Steps Milestone Checklists
The small steps you take now make a big difference in your child’s future success. The Steps Milestone Checklists for baby’s first year contains things most babies do by this age in the following areas:
- Social & emotional development

CDC Milestone Tracker App
At this stage of life, a baby’s development changes greatly from month to month. For an easy way to keep track of when your baby should reach certain milestones, download the free Center for Disease Control (CDC) Milestone Tracker app. The app also includes activities and learning tips for each age and an area where you can keep track of all your doctor appointments.
Children develop at different rates
Although most children learn to do things and reach specific milestones by a certain age, not all do. Different children develop at different rates.
If you suspect your child is behind, has a development delay or physical issues that hold him back, don’t delay. The sooner you get help, the faster your child will be able to cope with whatever challenge he faces.
