They learn that just because they can't see mom or dad at a certain time doesn't mean they don't exist. So now, your baby may begin to miss you when you're gone. This can lead to <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/sep-anxiety.html/">separation anxiety</a>&nbsp;&mdash;&nbsp;distress at your&nbsp;departure.</p> <p>While this might seem like a bad thing, it's actually very good&nbsp;&mdash;&nbsp;and marks an important leap&nbsp;in thinking. Comfort and reassure your baby to help him or her feel loved and secure.&nbsp;</p> <p>Doctors use certain milestones to tell if a baby is developing as expected. There's a wide range of what's considered normal, so some babies gain skills earlier or later than others. Babies who were born <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/preemies.html/">prematurely</a> reach milestones later. Always talk with your doctor about your baby's progress.</p> <p>Here are some things your baby might be doing:</p> <h4>Communication and Language Skills</h4> <ul> <li>communicates "no" by closing the mouth or turning away when finished eating</li> <li>understands the word "no"</li> <li>says "mama" and "dada" (but not just to parents)</li> <li>can wave goodbye and say "bye-bye"</li> <li>starts pointing to objects</li> </ul> <h4>Movement and Physical Development</h4> <ul> <li>sits without support, pulls to stand, and walks along furniture ("cruising")</li> <li>starts to grasp small pieces of food (such as pieces of "O"-shaped cereal)</li> <li>can hold one item in each hand at the same time</li> </ul> <h4>Social and Emotional Development</h4> <ul> <li>might be fearful of strangers</li> <li>misses caregivers when they leave</li> <li>seeks reassurance from caregivers (a baby starting to crawl, for example, will often "check back" with mom or dad while developing this new skill)</li> <li>attaches to "transitional objects" for security, such as stuffed animals or a favorite blanket</li> </ul> <h4>Cognitive Skills (Thinking and Learning)</h4> <ul> <li>understands "object permanence," the idea that an object or person exists somewhere even though the baby can't see the object or person at that moment (for example, a baby with this understanding will look for a toy that a caregiver hides behind a blanket)&nbsp;</li> <li>enjoys interactive games such as "peekaboo" and "so big"</li> <li>looks at the pages of a book while you <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/reading-babies.html/">read</a></li> <li>bangs objects on floor or table to create sound&nbsp;</li> </ul> <h3>When to Talk to Your Doctor</h3> <p>Every baby develops at his or her own pace, but if you notice anything that concerns you &mdash;&nbsp;however small &mdash;&nbsp;share it with your doctor. Always tell the doctor if your baby:</p> <ul> <li>shows no reaction when you leave the room</li> <li>cannot roll onto the belly</li> <li>hasn't lost newborn reflexes, such as the startle reflex&nbsp;</li> </ul> <p>Also, if you ever notice that your baby has lost skills he or she once had or shows weakness on one side of the body, tell your doctor.</p>El desarrollo de su hijo: 9 mesesLos médicos se basan en ciertos hitos evolutivos para saber si un bebé se está desarrollando según lo que cabe esperar.
