Baby’s Physical Development ⎼ Months 1-3
What to Expect the First Year details newborn reflexes and early motor skills during months 1-3, alongside feeding patterns and establishing initial sleep schedules.
Newborn Reflexes and Early Motor Skills
What to Expect the First Year thoroughly explains the fascinating newborn reflexes present from birth, such as the Moro (startle) reflex, sucking, and grasping. These are involuntary movements crucial for survival.
During the first three months, babies demonstrate gradual improvements in motor skills. Initially, movements are jerky and uncoordinated, but they progressively become smoother. Head control begins to develop, allowing for brief periods of holding the head up during tummy time.
The text highlights that not all babies develop at the same pace, and variations are normal. Parents are encouraged to provide opportunities for movement and exploration, fostering the development of these essential skills. Observing these early milestones is a rewarding experience for caregivers.
Feeding Patterns and Weight Gain
What to Expect the First Year provides detailed guidance on feeding patterns, covering both breastfeeding and formula feeding. Initially, newborns feed frequently, typically every 2-3 hours, gradually increasing the intervals as their stomachs grow. Weight gain is a key indicator of adequate nutrition during this period.
The resource explains expected weight gain ranges and emphasizes that individual babies will grow at their own pace. It addresses common concerns like snacking and grazing, noting that these can be normal behaviors.

Around four to six months, the introduction of solid foods begins, as detailed in the book, transitioning from exclusive milk to a more varied diet. Monitoring weight and consulting with a pediatrician are crucial throughout the first year.
Sleep Schedules and Patterns
What to Expect the First Year acknowledges that sleep is a significant concern for new parents. Newborns initially have irregular sleep patterns, sleeping in short bursts throughout the day and night. As they mature, babies gradually develop more predictable sleep schedules, though variations are common.
The guide addresses potential disruptions like sleep regression, offering strategies for managing these challenges. It emphasizes the importance of establishing a consistent bedtime routine to signal sleep time.
Understanding that individual sleep needs differ is crucial, and the resource encourages parents to observe their baby’s cues. Creating a safe and comfortable sleep environment is also highlighted as essential for promoting restful sleep throughout the first year.

Early Communication and First Words
What to Expect the First Year, as detailed in the 2025 updated edition by Heidi Murkoff, provides valuable insights into a baby’s burgeoning communication skills. The resource highlights that understanding a baby’s initial attempts at communication extends beyond actual words. It emphasizes recognizing coos, gurgles, and cries as early forms of expression.
The guide explores the fascinating development of pre-speech sounds and encourages parents to actively engage in “talking” with their baby, even before verbal responses are possible. Furthermore, it introduces the concept of “signing with baby” as a method to facilitate communication before a baby can verbally express their needs and desires, potentially reducing frustration for both parent and child. The book acknowledges the variability in timing for first words, reassuring parents that developmental milestones are reached at different paces.

Play and Interaction with Caregivers
What to Expect the First Year (2025 edition, Heidi Murkoff) underscores the critical role of play and interaction in a baby’s cognitive and social-emotional development. The resource details how simple activities, like reading to a baby, are foundational for building strong bonds and stimulating early learning. It emphasizes that consistent, responsive interaction is key to fostering a secure attachment.

Consistent, loving responses help build a secure attachment and foster emotional regulation skills in the developing child.

Common Concerns and Challenges
What to Expect the First Year addresses common issues like colic, fussiness, sleep regression, and exploratory behaviors, offering guidance and reassurance to parents.
Dealing with Colic and Fussiness
What to Expect the First Year acknowledges that colic and excessive fussiness are frequent parental concerns. The resource emphasizes understanding that these periods of intense crying, often without a clear cause, are typically developmental and usually resolve with time. It suggests various soothing techniques, including swaddling, gentle rocking, white noise, and offering a pacifier.
The guide stresses the importance of ruling out medical causes with a pediatrician, but also reassures parents that colic doesn’t indicate a long-term problem. It encourages self-care for parents, recognizing the emotional toll of prolonged fussiness, and suggests seeking support from partners, family, or support groups to manage stress effectively. Remember, these phases are temporary.
Addressing Sleep Regression
What to Expect the First Year prepares parents for potential sleep regressions – periods where a previously good sleeper suddenly wakes more frequently or resists naps. These regressions often coincide with developmental leaps, like learning to roll, crawl, or teethe, and are typically temporary. The guide advises maintaining a consistent bedtime routine, even during regression, to provide comfort and security.
It suggests avoiding introducing new habits during this time, as it can reinforce the disrupted sleep pattern; The resource emphasizes patience and reassures parents that regressions are normal. It also recommends checking with a pediatrician to rule out any underlying medical causes for the sleep disturbance, and prioritizing parental self-care during these challenging phases.
Managing Biting and Exploring Genitals
What to Expect the First Year acknowledges that biting and genital exploration are common behaviors during infancy, often stemming from curiosity and teething discomfort. The guide stresses the importance of a calm, non-punitive response to biting, firmly stating “no biting” and redirecting the baby’s attention. It explains that babies explore their bodies as they discover themselves and their surroundings.
The resource advises parents to ensure a safe environment, minimizing opportunities for biting others and offering appropriate teething toys. Regarding genital exploration, it suggests distraction and loose-fitting clothing. What to Expect emphasizes that these behaviors are usually a phase and not indicative of any underlying issues, but encourages seeking professional advice if concerns persist.

Health and Safety Considerations
What to Expect the First Year details vaccination schedules, well-baby checkups, and recognizing illness signs. Creating a secure home environment is paramount for a baby’s wellbeing.
Vaccination Schedule and Well-Baby Checkups
What to Expect the First Year emphasizes the critical importance of adhering to the recommended vaccination schedule. These immunizations protect your baby from serious, potentially life-threatening illnesses. Regular well-baby checkups are equally vital, allowing healthcare professionals to monitor growth, development, and overall health.

The book details what parents can anticipate at each monthly visit, ensuring they are prepared with questions and observations. Staying proactive with vaccinations and checkups contributes significantly to a baby’s healthy start in life, offering peace of mind for new parents navigating this crucial first year.
Recognizing Signs of Illness
What to Expect the First Year provides essential guidance on identifying potential illness in infants, as their ability to communicate discomfort is limited. Key signs include fever, lethargy, poor feeding, persistent crying, difficulty breathing, and changes in stool patterns. The book details specific symptoms associated with common childhood illnesses, empowering parents to seek timely medical attention.
It stresses the importance of trusting parental instincts; if something feels “off,” consulting a pediatrician is always recommended. Early detection and intervention are crucial for managing illnesses effectively and preventing complications. Knowing what constitutes a normal developmental phase versus a sign of illness is a key takeaway, fostering confident and informed caregiving during the baby’s first year.
Creating a Safe Home Environment
What to Expect the First Year emphasizes the critical importance of babyproofing to ensure a safe environment as mobility increases. This includes securing furniture to prevent tipping, covering electrical outlets, and installing safety gates at stairs.
