The nine months of pregnancy seem endless for many expectant mothers. In reality, it is amazing how much a baby grows and changes during that time. In fact, many of those changes, including the development of a heartbeat, occur before the expectant mother even knows she is pregnant, according to MayoClinic.com.
The development of a baby in utero is truly remarkable. Only a few weeks pass between the time an egg is fertilized and the heart begins to beat. While the organs may grow rapidly, some are not fully functional until the baby is full-term and ready to be born. Others, such as the heart, are functional before the end of the first trimester of pregnancy.
Now that your baby is born, you get to enjoy watching her reach several milestones over her first year of life. Baby development milestones include the big ones, such as walking for the first time and saying her first words, as well as smaller, but equally important ones, such as being able to lift her head on her own and recognizing who you are.
When a baby starts to walk, he unofficially becomes a toddler. When most people speak of toddlerhood, they are referring to children between 1 and 3 years of age. Toddlers often make major changes, especially in regards to locomotion, thinking and talking. One-year-olds master walking and mobility, while 2-year-olds work on expanding their vocabulary. Toddlers learn to master their bodies and progress from walking to climbing and running. They learn names of body parts and are constantly refining their fine- and gross-motor skills. They become more independent and imitative. Children reach milestones based on their own timetables, but there are averages of when to expect new developments.
The emotional development of adolescents seems ever more complex in a changing and challenging world. With new ways of communicating with one and another and the ability to remain in close touch with parents, or to “turn parents off,” adolescents pose a challenge to themselves and those who care about them.
