Fussy phase

"Whining" refers to the nagging, tearful behavior children use to show that something is wrong, even if parents can't always tell what it is. The child whines, is unhappy, wants to be held, and is hard to distract. “Fussy phase” is a term used in everyday family life and is not a medical diagnosis.

Even infants go through such phases. For many babies, crying increases around the second week of life and subsides again by three to four months, often peaking in the afternoon and early evening. Later, fussiness in toddlers occurs during the autonomy phase, which begins toward the end of the second year of life and lasts until around their fourth birthday.

A child doesn’t whine to annoy parents. They don’t yet have the words to express what they’re feeling, so they use the voice they have. To parents, this often feels like it’s happening for no reason, because the child—who is well-fed, dry, and well-rested—remains restless nonetheless. It is precisely this mystery that makes whining phases so exhausting.

Developmental leaps are a common trigger. Before a child masters a new skill, many changes are taking place in their mind and body. This can be overwhelming, and the frustration of not yet being able to do something new is expressed through whining and crying. Shortly before they start grabbing, crawling, or saying their first words, some children are therefore particularly clingy.

There are also simple physical reasons: tiredness, hunger, teething, or too many new experiences on a busy day. Infants quickly reach the limit of what they can process and then react by becoming overstimulated. For toddlers in the autonomy phase, the child wants to do many things on their own, fails due to their own clumsiness, and becomes angry or tearful as a result. This, too, is part of normal development.

Experts emphasize that the “autonomy phase” is a more appropriate term than the older term “defiance phase.” The focus is on the child, who is experiencing themselves as a separate person and detaching somewhat from their parents. The whining is simply the soundtrack to a major step: growing independence.

Most periods of fussiness and restlessness are harmless and go away on their own. A healthy child who can be calmed and comforted from time to time, feeds well, and is gaining weight is usually just going through a difficult phase.

Parents should take a closer look if the pattern doesn’t fit the picture. Pediatricians refer to a baby as a “cry baby” if an infant cries for more than three hours at a time on at least three days a week for more than three weeks, without any apparent reason. Other signs that a medical evaluation is needed include:

• persistent problems falling asleep and staying asleep
• difficulties with feeding or unusual weight gain
• a child who is almost impossible to soothe despite all attempts
• Parents who feel increasingly helpless and at the end of their rope

Such observations are a reason to seek medical advice, even if physically everything is usually fine.

For infants, calm, repetitive stimuli have a soothing effect: being held, a soft voice, gentle humming, steady movement, a familiar scent. It’s best for parents to use these methods early on, before the crying escalates. A hectic day can be managed by reducing stimuli and maintaining a consistent schedule for sleeping and eating. A walk in a baby sling, a dimmed room, or the steady hum of the washing machine can calm many babies more quickly than any amount of fidgeting.

With toddlers, it helps to know what’s going on. If you view the phase of asserting autonomy as a normal step in their development, you’ll take the whining less personally and be able to set boundaries more calmly. Your child will find their balance again through your calmness—this is called co-regulation.

Your own strength is just as important. Whining phases take a toll, especially when you’re sleep-deprived. Schedule short breaks, take turns with another person, and seek support before tension turns into deep exhaustion. Self-care isn’t a luxury here—it’s essential for staying calm when you’re at the end of your rope.

The first place to turn is your pediatrician’s office. There, you can determine whether all the fussing is just part of a challenging phase or if there’s something else going on. In many regions, there are also crying clinics, counseling centers for parents with babies and toddlers, and family centers that offer in-person support.
