Newborn Development in Weeks 1–3

Is your baby sleeping almost all day, wanting to feed frequently, or preferring to be held constantly? In the first few weeks of life, many parents wonder if their baby is developing normally.

First of all: In this early phase, there is no fixed routine yet. Sleep, nutrition, and development change almost daily—and each baby does this at their own pace.

In the first days and weeks, your baby is adjusting to life outside the womb. Breathing, digestion, temperature regulation, and sleep need to settle in. At the same time, their senses are starting to work: They become more aware of light, sounds, smells, and touches, and recognize familiar voices, scents, and your heartbeat. These early bonding moments lay the foundation for their further development.

What You Can Observe Now

You might notice that your baby:

  • has short awake periods with an attentive gaze
  • responds particularly to your calm voice
  • calms down quickly with physical contact, being held, or sucking
  • shows strong grasping, sucking, and stepping reflexes
  • sleeps and feeds very irregularly

Many newborns sleep a total of 16 to 18 hours a day—spread over many short sleep phases. Frequent breastfeeding or feeding is also completely normal in the first weeks.

What Your Baby Needs Now

In this phase, your baby primarily needs security and comfort.

Helpful are:

  • plenty of closeness, skin contact, and loving touch
  • calm voices and as few strong stimuli as possible
  • regular breastfeeding or feeding on demand
  • being held and physical contact for comfort
  • first gentle day-night routines—even if your baby doesn't understand the difference yet

You don't need to stimulate your baby right now. Your closeness, your voice, and your reliability are the most valuable things you can give them.

Nutrition and Health

Breast milk or infant formula is the only source of nutrition in the first weeks.

Additionally, these topics are often part of the first weeks of life:

  • the normal development of stool from meconium to breast milk or formula stool
  • umbilical care and weight development
  • newborn screening and the preventive examinations U2 and U3
  • mild skin changes like dry skin or newborn acne, which are usually harmless and temporary

How You Can Support Your Baby

  • Speak calmly to your baby and maintain eye contact regularly.

  • Hold your baby often—closeness helps them regulate and provides security.

  • Watch for signs of tiredness or overstimulation and ensure they get enough rest.

  • Trust your instincts: Your baby doesn't need entertainment right now, but rather loving companionship.

Milestones

  • Between the 1st and 4th week, your baby usually moves their arms and legs symmetrically and feeds effectively from the breast or bottle.
  • By around the 8th week, they turn their head to the side when lying on their back and increasingly respond to familiar voices and touches.

In Summary

The first weeks of life are a time of settling in—for your baby as well as for you. A fixed sleep or feeding schedule is not yet expected. What matters most now is closeness, security, and time to get to know each other. Everything you experience together in these first weeks forms an important foundation for your child's further development.
