Child Temperament & Examples – Easy Baby vs Difficult Baby

The primary distinction between easy and difficult babies lies in their bodily functions’ regularity and reactions to stimuli. Easy babies exhibit more predictable bodily functions and positive reactions, while difficult babies show the opposite.

Research shows that for difficult children, low emotional support correlates with poorer outcomes, while positive parenting is associated with performance beyond their easy temperament counterparts. That’s because children with difficult temperaments are more affected by the quality of parenting, both positively and negatively. This characteristic, called differential susceptibility, highlights the importance of adopting an authoritative parenting style rather than the tough-love approach conventional wisdom suggests.

The main difference between an easy baby and a difficult baby is that an easy baby has more regular bodily functions and more positive reactions to stimuli. In comparison, a difficult baby has less regular bodily functions and more negative reactions to stimuli.

All parents wish they had easy babies.

Parents who have difficult babies often envy those who have calm ones.

But research shows that having a child with a difficult temperament is actually not a bad thing.

In this article, we will explain what temperament is, look at the three types of temperament and show you what to do if you have a difficult baby.

As parents of multiple children already know, each child is different when they are born even though they are raised in the same home.

Right from the beginning, newborns already show distinct styles of responding to the environment.

Each of them has their individual child’s temperament and baby personality types.

What Is Temperament

Temperament is a child’s early-appearing variation in emotional responses and reaction to the environment.

Child temperament is a result of biological and environmental factors working together throughout a child’s development since conception rather than based entirely on genetics​1,2​.

There are different categorizations of temperament by different researchers. 

The most influential research is conducted by doctors and psychologists, Chess and Thomas​3​.

Their well-known New York Longitudinal Study lasted for several decades (1956-1988) and found 9 temperamental traits that can be commonly identified in young children.

What is Temperament in Psychology? 9 Temperament Traits (Thomas and Chess)

1. Activity

The level and extent of motor activity.

2. Regularity

The rhythmicity, or degree of regularity, of functions such as eating, elimination, and the cycle of sleeping and wakefulness.

3. Initial Reaction

The baby’s response to new things or new people, in terms of whether the child approaches the new experiences or withdraws from them.

4. Adaptability

The adaptability of behavior to changes in the environment.

5. Sensitivity

The sensory threshold, or sensitivity, to stimuli.

6. Intensity

The energy level or the intensity of reactions.

7. Mood

The child’s general mood or “disposition”, whether cheerful or given to crying, pleasant or cranky, friendly or unfriendly.

8. Distractibility

The degree of the child’s distractibility from what he is doing.

9. Attention span and persistence

The span of the child’s attention and his persistence in an activity.

Types Of Temperament in Child Development

Among the nine types of temperament trait categories, researchers found that six of them, activity, regularity, initial reaction, adaptability, intensity, and mood, tend to cluster together to form three types of temperament.

The three types of children temperament styles are:

  • easy temperament
  • difficult temperament
  • slow to warm up temperament

Easy Temperament

Easy temperament is characterized by regular bodily functions, a positive approach to new situations, adaptability, a positive mood, and a non-intense reaction to stimuli.

Raising these children is relatively easy because they respond favorably to various child-raising practices. They readily adapt to different parental handling.

Easy temperament examples

During a birthday party, an easy child will join in the party games easily without any fuss.

They will also be able to switch from activity to activity without difficulty.

Difficult Temperament

Difficult temperament is characterized by irregular bodily functions, withdrawal from new situations, slow adaptability, negative mood, and intense reaction.

Some difficult babies are also highly sensitive babies. Raising these children is difficult from the get-go.

But this is by no means the definition of being “difficult”.

Parents know when they have difficult babies.

Difficult babies with an intense and highly reactive temperament tend to be crying a lot.

They cry hard, they cry loudly and they are hard to soothe.

They are also cranky babies.

They tend to have sleep problems.

They have a hard time falling and staying asleep.

When they wake up in the middle of the night, they have trouble going back to sleep.

These difficult babies are also called colic, spirited, stubborn, or high need babies.

Colic in babies is particularly frustrating for overwhelmed and exhausted parents.

Difficult temperament examples

It may be hard for them to wait patiently for their turn.

When switching from playing games to going into the party room, they may have a tantrum because they are in the middle of a game.

Slow To Warm Up Temperament

The slow to warm up child is characterized by low activity level and low intensity of reaction although they also have a tendency to withdraw from new situations, slow adaptability, and somewhat negative mood.

A slow-to-warm-up child is a cautious child.

These kids can adapt to new situations if they’re allowed to do that at their own pace.

However, if pressured to do so, these children may fall back to their natural tendency to withdraw.

Slow-to-warm-up temperament examples

When a slow-to-warm-up child first arrives at the party, they may trail behind their parents and not join the other kids.

After watching other kids play for twenty minutes, they cautiously join in and have fun.

Roughly 40% of babies have the easy temperament, 10% difficult, and 15% slow to warm temperament. 30% of children do not fall into any of the three identified types.

Difficult Temperament And Tough Love Parenting

The relationship and influence between a baby’s temperament and parenting are bidirectional​9​.

Difficult children’s temperaments tend to elicit a tough response and inconsistent discipline from parents​10​.

When a baby cries incessantly, you may have the urge to shout at them to stop. And when your difficult child yells at you, it is natural that you want to yell back.

Tough love parenting is therefore sometimes used by parents whose children have a difficult temperament.

However, according to research, low emotional support, e.g. tough-love parenting, tends to raise children who have worse outcomes.

Studies find that there is less mental well-being among people raised by authoritarian parents​11​.

But you can often hear people who boast about being raised by tough parents and turning out fine.

Why is there a discrepancy?

This difference in resilience can be explained by the Diathesis Stress Model.

According to the Diathesis-Stress Model, people who have a predisposition or vulnerabilities to suffer from a psychological disorder require a lower threshold to trigger the disorder.

When a difficult child’s disposition is more vulnerable, if they are parented by tough parents, they are more likely to develop psychological disorders later.

So tough love is simply not the answer to raising children with a difficult temperament.

It can make things worse.

By remaining calm, responsive, and sensitive, it may take a long time to get through to your child and the process may be painstaking.

But at the end of the day, the reward of being a good parent will be tremendous.

Is Easy Baby Better Than Difficult Baby?

There is no such thing as a good temperament or bad temperament.

Many parents of babies with irregularities wonder, “Is my baby difficult?”

If you have an easy baby, congratulations! You probably have more sleep than many other parents.

We envy you!

But if you have a difficult one, you have more work cut out for you.

Caring for a difficult baby is exhausting and worrisome.

The most worrisome aspect is perhaps the fact that difficult baby temperament types are associated with more behavior problems and emotional disorders later in life​4,5​.

However, do not despair if you have a difficult baby. 

There is actually good news for you.

Differential Susceptibility

Studies have shown that differential susceptibility plays a big role in a child’s outcome​6​.

That means temperament by itself does not determine how a child will turn out because of its cross-over interaction with the environment​7​.

What Is Differential Susceptibility?

Differential susceptibility means young children with a difficult temperament are disproportionately affected by parenting. They react more (more susceptible or more sensitive) to the quality of parenting than easy children, for better and for worse.

When raised with good parenting, a kid with a difficult child temperament tends to do better in cognitive, academic, and social adjustment than their easy counterparts.

On the other hand, when parenting is bad, a difficult baby will fare worse when they grow up.

So you should be thrilled if you have a difficult or sensitive baby.

Sensitive babies actually have a better chance to succeed, if you do your part in providing good parenting.

Child Temperament Types And Parenting Style

In studies on differential susceptibility, parenting quality is defined as good when parents show a high level of emotional and autonomy support. Bad parenting is when the parents show a low level of emotional and autonomy support​8​.

This definition is similar to one of the criteria used to categorize the four Baumrind parenting styles.

Among the four styles, authoritative parenting, which provides high emotional and autonomy support, is the best according to numerous studies.

It comes as no surprise that such a parenting style also provides the most positive impact on difficult children.

And because of this differential susceptibility property, it is even more important for parents of difficult babies to adopt an authoritative parenting style.
