The Baby Book summary

A newborn’s early weeks are full of surprises. Just as they’re adjusting to life outside the womb, you’re adjusting to life as a parent. Understanding what’s normal can help you respond with confidence and ease.

Newborns breathe in irregular patterns, sometimes even pausing for a few seconds before resuming. While this can be alarming at first, it’s part of their natural development. Noisy breathing, sneezing, and occasional gagging are also common as they clear tiny nasal passages and adjust to breathing air. If your baby sounds congested, it’s often due to lint, dust, or milk residue – not a cold. Keeping their environment free from irritants like smoke and perfumes can help them breathe more comfortably.

Breastfeeding is one of the most effective ways to nourish and protect a baby, providing everything they need to grow while also supporting a mother’s recovery. It’s a deeply personal choice, and while it offers unmatched benefits, it isn’t always possible or the right fit for every family. Understanding how it works and how to manage common concerns can make breastfeeding easier and more rewarding.

Your body efficiently prioritizes milk production, drawing from nutrient stores to provide for both you and your baby. You’ll need an extra 300 to 500 calories a day, but quality matters. A diet rich in whole grains, lean proteins, and healthy fats maintains energy and supports milk production. Calcium is essential, but despite common concerns, breastfeeding doesn’t weaken bones – women who breastfeed usually regain bone density after weaning, often ending up stronger than before pregnancy. Omega-3s in breast milk, especially DHA, support brain development. Eating oily fish or taking a supplement ensures your baby gets enough.

In Bali, babies don’t touch the ground for the first six months of life. Instead, they are carried by their parents or family members throughout the day, kept close in a way that meets their needs for security, comfort, and connection. This approach is an instinctive way of caring for a baby that has existed for centuries. Carrying your baby for extended periods leads to a calmer, happier infant while making daily life easier for you.

Babies who are carried tend to cry less. A study found that infants held for at least three hours a day fussed 43% less than those who weren’t. The motion of being carried mimics the womb experience, creating a sense of security that helps regulate your baby’s emotions, sleep, and even digestion. Wearing your baby also keeps them in a state of quiet alertness, the optimal condition for learning. Instead of lying passively in a crib or stroller, a carried baby is constantly observing, hearing conversations, and engaging with the world. This exposure supports language development, cognitive growth, and early social skills.

Ever heard someone say they “slept like a baby” after a good night’s sleep? As any new parent will tell you, this saying isn’t always accurate – infant sleep is far more complex. Unlike adults, babies don’t slip into deep sleep right away. Instead, they begin in a light sleep phase that lasts about twenty minutes before entering deeper sleep. If you put your baby down too soon, they’re likely to wake up. Their sleep cycles are also much shorter, about an hour, meaning they naturally wake more often during the night. Frequent waking isn’t a flaw in their development – it’s how they’re designed. Waking ensures they can signal for warmth, comfort, or food when they need it, which may even be a built-in safeguard against Sudden Infant Death Syndrome, or SIDS.

The expectation that babies should sleep through the night is based more on parental exhaustion than on biological reality. Sleep training methods that encourage leaving babies to cry ignore the fact that nighttime parenting is just as important as daytime care. Babies don’t learn independence by being left alone at night; they learn security from consistent, comforting responses. The belief that letting babies cry it out teaches them to sleep on their own is misleading. Studies show that prolonged distress increases stress hormones, which can affect brain development. Babies who are soothed when they wake develop healthier long-term sleep habits.

A baby doesn’t grow in isolation. Every developmental milestone is shaped by the interactions they have with you. The more responsive and engaging that your care is, the smoother their progression from one stage to the next will be. But growth isn’t just about your baby – it’s about both of you. As they develop new skills, you become more attuned to their needs, their cues, and their personality. This mutual learning process builds a strong foundation for communication, trust, and a deeper connection.

The way you and your baby interact from birth plays a direct role in their development. Babies aren’t passive recipients of care – they actively shape the way you parent, just as you shape their behavior. A newborn cries to signal discomfort, and as you respond, they refine their communication, moving from crying to gestures and facial expressions. This process strengthens their social and emotional skills while helping you become more confident in reading and responding to their needs.

One moment, your baby is happy to sit in one spot; the next, they’re on the move, exploring everything in sight. The transition from babyhood to toddlerhood is fueled by three major developments: walking, talking, and thinking. With each step, word, and discovery, your child gains independence – but they still need your support.

Toddlers quickly go from wobbly steps to running, climbing, and jumping. Every fall is followed by determined attempts to try again. Walking itself becomes a game, with spinning, stomping, and exaggerated steps. This newfound mobility brings endless curiosity – buttons must be pressed, drawers emptied, and every object examined. Close supervision becomes essential as they test boundaries.
