Curated by Claudia Shannon / Research Scientist / ishonest


A fussy baby can send even the calmest parent into a panic. For many parents, these mood swings are unpredictable and seemingly never-ending. That’s where The Wonder Weeks come in.

Doctors van de Rijt and Plooij claim there is a predictable pattern to fussy behavior. Using their learnings from 35 years of observational research, they have created a chart to try to predict when your baby will be fussy or pleasant, and for how long. Their conclusions are based on their observations and not on scientifically controlled studies. So don’t worry if your baby does not fit their pattern or behave in a predictable way. Not all parents find that The Wonder Weeks idea works for them.

Fussy is a relative term. Each baby’s version of fussy will be unique to them. You may also find that your baby’s fussy behaviors change over time. It’s important to remember not to compare your baby to other babies, including siblings.

For a new parent, identifying a baby’s fussy behavior may take some time, but by paying attention to the signs your baby is giving you, you may be able to identify their moods and find patterns in their behavior.

Getting through the fussies

When your baby is going through a leap period, getting through your day can leave you feeling like you’ve just run a marathon, minus the runner’s high. Simple tasks like washing the dishes or folding the laundry can take hours. You’ll regularly have to stop what you’re doing to comfort a crying, clingy baby. To add to your exhaustion, babies sometimes wake more during the night while going through a leap, so you may be sleep-deprived.

Here are some tips to help you make the most of your baby’s leaps:

Consider wearing your baby in a soft carrier, such as the Baby K’tan baby carrier. Wearing your baby can help soothe your child without keeping you from leaving the house or getting through your to-do list. Make sure to follow the carrier’s instructions to avoid injury to your baby or yourself.

Take a time out. A 2014 study found evidence that babies may be able to sense the moods of their parent. If you become overly stressed by your baby’s fussiness, put them in a safe area, like a crib, or hand them off to another caregiver, and take a time out. Go to another room while you regroup, or if the crying is really bothering you, consider leaving the house for a short time.

Give your baby a bath, if they enjoy them. Sometimes a bath can help reset your baby’s mood, plus the warm water can be soothing.

Take your baby for a walk. A change of scenery can do wonders for baby’s mood and yours.

Experiment with new games, sounds, or textures, or retry something from the past. As your baby’s worldview changes, so, too, will their response to stimuli. That rattle they’ve barely touched may suddenly be incredibly exciting, or you can show them a new use for their lovey, like for a game of peek-a-boo.

Lower your expectations. Babies are demanding on a good day, but during a leap, those demands can be all-consuming. Put off your housework and remove nonessential things from your to-do list, or enlist a friend or family member to help you get stuff done.

Plan ahead. If you see that a leap is coming, try to get ahead of it. Consider freezing several make-ahead dinners and check as many things off your to-do list as you can. You may even want to consider putting off unnecessary outings until after a leap.


Babies are constantly changing. The world is a new, exciting, and sometimes scary place for them. As their caregiver, you can help them navigate through their development leaps. Provide stimulating, age-appropriate games and activities to help them learn new skills. Set aside extra time to get things done, and plan for extra snuggle sessions during your baby’s leap weeks. You never know, you may come to miss these clingy periods when your child’s no longer a baby.
