The infant does not regulate its body temperature or sleep-wake cycles autonomously for several weeks. Supporting the first months of a baby requires mastering some specific physiological mechanisms, far beyond the lists of equipment found everywhere. Here we address the technical points that truly condition the safety and development of the infant during this period.
Sleeping safety: criteria that reduce the risk of sudden infant death
Placing the baby on their back, on a firm mattress, and in a bed free of soft objects remains the reference configuration endorsed by pediatric health authorities. We observe that this recommendation, although well-known, is still poorly applied in daily practice.

The mattress must fit perfectly in the bed, with no gaps at the edges. No pillows, duvets, bumper pads, or stuffed animals should be in the sleeping space during the first months.
- Always place the infant on their back, including for naps, even after a feeding (the risk of aspiration is lower than the risk of being placed on the stomach)
- Prefer a sleep sack suitable for the season rather than a blanket, which can ride up over the face
- Maintain the room temperature around 18-20 °C and avoid overdressing, often underestimated as a risk factor
- Place the crib in the parental bedroom for the first few weeks, while avoiding bed-sharing when a parent consumes alcohol, tobacco, or sedatives
Many resources discussing babies on Maman au Quotidien detail these guidelines in addition to institutional fact sheets, allowing for cross-referencing information before making decisions about arrangements.

Hunger signals and infant feeding rhythm: beyond the bottle-clock reflex
Feeding on demand takes precedence over any fixed schedule during the first weeks. Waiting for an infant to cry to feed them means responding to the last hunger signal, not the first.
Early signs of hunger are subtle: sucking movements, turning the head towards the breast or bottle, hands brought to the mouth. Recognizing these signals allows for anticipating feeding and reducing the infant’s agitation before eating.
Monitoring weight gain in the first weeks
A weight loss of up to one-tenth of the birth weight is physiological in the first days. Returning to birth weight should occur within two weeks. Beyond that, a quick pediatric consultation is warranted.
The number of wet diapers remains the best indirect indicator of hydration: we recommend counting at least five to six well-soaked diapers per day starting from the fifth day of life. An infant who does not wet their diapers sufficiently should be seen quickly.
Milk production typically occurs between the second and fifth day after birth. It may be accompanied by breast engorgement and fatigue, which can sometimes complicate the establishment of breastfeeding. Support from a lactation consultant or a midwife trained in breastfeeding makes a measurable difference in the duration of exclusive breastfeeding.
Neuro-sensory development: milestones to monitor month by month
Monitoring sensory development is often relegated to medical visits, while parents are the primary observers. Early detection of a visual or auditory disorder significantly changes the prognosis.
Vision and hearing in the first three months
The newborn perceives strong contrasts and focuses on a face at close range from the first weeks. By two months, eye tracking (following a slowly moved object) should be present. Its absence warrants a report during the second-month consultation.
On the auditory side, startling at loud noises and calming to the parental voice are simple indicators. The neonatal hearing test performed in maternity does not detect all hearing impairments, especially those that appear gradually. Staying attentive to sound responsiveness over the weeks remains necessary.
Motor skills and axial tone
Head control is expected to be stable around the third month. Before that, supervised tummy time (a few minutes a day, baby awake) strengthens neck and back tone. This positioning, distinct from sleeping, also helps limit positional plagiocephaly.
Parental mental health in the postpartum period: a direct factor in the infant’s well-being
The extreme fatigue of the first months is not an inevitable phase to accept without reacting. Recent public health publications now include the identification of parental depressive symptoms as a component of postnatal follow-up.
An exhausted parent makes less safe decisions for the infant, whether in sleeping, feeding, or supervision. Social isolation amplifies this risk.
Among the warning signs to be aware of:
- Persistent sadness or disproportionate irritability beyond two weeks after birth
- Difficulty forming an emotional bond with the infant, feeling of detachment
- Parental sleep disturbances even when the baby sleeps, anxious ruminations
The baby blues, common in the first days, is distinguished from postpartum depression by its duration. Beyond two weeks of symptoms, a consultation with a healthcare professional (midwife, doctor, psychologist) is recommended. This is not a sign of parental fragility; it is a preventive act that protects the parent-child bond.
Ultimately, monitoring the first months relies on three technical pillars: the safety of the sleeping environment, reading feeding signals, and vigilance over sensory development. Integrating parental mental health into this equation recognizes that the quality of care for the infant directly depends on the state of the parent providing it.
