Developmental Milestones

Delayed Developmental Milestones

Why tracking normal development is an essential part of childcare

Witnessing your child’s “firsts” — first steps, first words, that first genuine smile — is one of the most rewarding parts of parenthood.

But these moments are about more than just giving the parents some great memories. They are also developmental milestones that serve as reassuring reminders that your child is growing as expected.

Baby Learning to Walk

When babies suffer from birth injuries, it can be difficult to predict how it might affect them later in life. The first signs of physical or neurological damage may only become clear months later once they’re failing to develop new skills.

Parents may express concern that their child is not sitting up, standing, or communicating as expected during scheduled wellness checkups. The doctor may also notice additional concerns like an overly stiff or floppy appearance. This is typically when the child first receives an official diagnosis for their disabilities, such as autism or cerebral palsy.

Babies who suffer from birth injuries have a higher chance for delayed developmental milestones later in life. Brain damage at birth, in particular, can cause permanent complications like hypoxic ischemic encephalopathy (HIE), cerebral palsy, and intellectual disabilities.

Children with these kinds of injuries usually need significant treatments, therapies, procedures, and intensive care to manage their disabilities. This care is never cheap, often placing a heavy financial strain on families who are already grappling with emotional grief.

Paying attention to your baby’s developmental milestones can help you stay alert for signs of disabilities or complications. On this page, we will cover important milestones throughout early childhood and the common red flags to watch out for. We will also discuss your legal options when you suspect your child’s delays stem from preventable injuries at birth.

What Are Developmental Milestones?

Developmental Milestone Delays

Developmental milestones are significant events, skills, or accomplishments that children learn as they age. Parents and pediatricians can use them as reassurance that the baby is growing up normally without issues.

It’s true that children sometimes progress at slightly different rates. One nine-month-old might be walking while another is just starting to crawl. However, a baby or child who misses several milestones is cause for concern.

With some conditions – like cerebral palsy, for example – early intervention is crucial. Therapies, surgeries, medications, caregivers, and assistive technology can improve a child’s future and help them progress as far as possible.

Types of Developmental Milestones

There are four main categories that many pediatricians and early childhood specialists use to classify a child’s developmental milestones:

Baby playing
  • Movement/Physical Development: Children’s ability to use their bodies for things like sitting, walking, and eating. Includes large movements (gross motor skills) and small, more coordinated movements (fine motor skills).
  • Social/Emotional Domain: Children’s ability to relate to others and express their feelings and emotions.
  • Language/Communication: Children’s ability express their needs, share their thoughts, and understand what others say to them.
  • Cognitive: Children’s ability to learn, solve problems, explore their environments, and use skills like counting and learning the alphabet.
Developmental Milestone Domains

It’s important to note that some goals or achievements fit into more than one category. For example, a child’s ability to follow instructions speaks to both their communication and cognitive skills.

Additionally, some milestone domains can break into smaller subcategories. Developmental specialists will want to closely monitor a child’s hearing, speech, vision, and physical milestones alongside the other categories.

Hearing Development Delays

Hearing Development Delays

Hearing developmental milestones track how babies and children respond to sounds, voices, language, and communication cues as they grow up.

Strong hearing skills are crucial to speech development, learning, and building strong social and emotional bonds.

About Hearing Delays


Speech Development Delays

Speech Development Delays

Developmental speech milestones focus on how children learn to communicate through sounds, words, gestures, and sentences.

Speech development relies primarily on healthy brain function, muscle coordination, and hearing. Babies with brain damage or other birth injuries may have a higher risk for speech impairments and delayed speech milestones.

About Speech Delays


Physical Development Delays

Physical Development Delays

Physical developmental milestones measure how children build muscle strength, coordination, balance, and movement skills.

Birth injuries to the brain or spinal cord injuries can sometimes disrupt neuromuscular control and cause conditions like cerebral palsy. Children with these injuries will likely experience at least some degree of impaired gross motor function.

About Physical Delays


Visual Development Delays

Visual Developmental Delays

Visual developmental milestones evaluate children’s ability to focus, track and recognize objects, process visual input, and coordinate vision with movement. Strong vision can support learning, communication, social development, balance, and coordination.

Birth injuries can sometimes damage a child’s visual processing centers and lead to vision impairments. Common problems that cause developmental delays include cortical visual impairment (CVI) or retinopathy of prematurity (ROP).

What Are Some of the Causes of Developmental Delays?

Developemental Delays

Babies can be at risk for future developmental delays or disabilities because of the following factors:

Genetics

Genetic Defects

Genetic issues often cause conditions like Down syndrome and autism. These can lead to delayed developmental milestones across multiple domains for the baby.

Medical providers should be able to recognize when a child might have one of these conditions through prenatal testing screenings.


Pregnancy Complications

Preeclampsia

Pregnancy complications like high blood pressure (preeclampsia), gestational diabetes, anemia, or maternal infections can increase the baby’s risk for harm.

When medical professionals fail to properly recognize that risk or respond to it, these issues can complicate delivery. If a baby sustains birth injuries as a result of their mother’s complications, they are more likely to experience delayed developmental milestones.

About Preganancy Complications


Labor and Delivery Complications

Labor Complications

Some of the more serious issues during pregnancy can result in labor and delivery complications. Issues like prolonged labor, delayed c-sectionsumbilical cord problems, fetal distress, or misusing delivery instruments can cause severe birth injuries.

When these injuries cause brain damage to the baby, it can impact their development after birth. Injuries like brain bleeds and oxygen-deprivation-related conditions like hypoxic-ischemic encephalopathy (HIE) have serious potential to cause developmental delays in life.

About Labor Complications


Premature Birth

Premature Birth Complications

A child’s gestational age at birth can make a difference as they progress along average developmental timelines.

Premature infants are far more likely to have neurodevelopmental disabilities.

When observing whether your child is hitting their goals, remember to adjust expectations based on their gestational age. For example, a baby three months early might be three months late when meeting their milestones.

About Preterm Birth


Inadequate Neonatal Care

Birth Complications

Babies may need neonatal resuscitation immediately after birth to prevent oxygen deprivation. Also, some babies are at risk for birth complications that can cause serious injuries.

Conditions like neonatal hypoglycemia, hyperbilirubinemia (jaundice), and kernicterus (a serious disorder that causes brain damage) require immediate treatment. When medical providers don’t respond properly, a small injury can progress into one that causes developmental delays later in life.

About Birth Complications

Did Medical Malpractice Cause My Child’s Developmental Delays?

Birth Injury Malpractice

The parents of children with developmental delays often want answers. They want to know what is causing these delays. Was it genetics? Was it something they did? Or was it a result of negligent delivery room errors that caused preventable brain injuries?

Miller Weisbrod Olesky's dedicated birth injury lawyers want to help you find those answers.

We have seen hundreds of cases where doctors, midwives, or nurses breached their duty of care while delivering newborns. Mistakes like missing abnormal fetal heart rates or using excessive force during delivery can cause permanent injuries. These birth injuries have lasting impacts on a child’s growth and can prevent them from gaining new skills.

Overcoming these challenges requires a myriad of intervention treatments, therapies, and evaluations. Not all families have the resources to ensure their child receives the early intervention they need to stay on track. But speaking with a knowledgeable birth injury attorney can be the first step in securing those resources.

Sometimes families are hesitant to reach out to a medical malpractice attorney or law firm. They may feel overwhelmed by their circumstances or feel worried about proving the strength of their medical malpractice claim.

But the only way to find out if you have a birth injury case is to reach out for help. Talking to an attorney who understands how birth injuries delay important milestones can help you better understand your legal options.

What Is the Statute of Limitations in a Birth Injury Case?

Birth Injury Statute of Limitations

statute of limitations (SOL) is a law that sets a time limit on how long an injured person has to file a lawsuit after an accident. It is essential to understand that statutes of limitations vary based on the case and the state where you file. For instance, the deadline for birth injury claims is typically different from other claims, such as injury to private property.

Generally, the clock starts ticking on the date the injury occurred. However, there are exceptions to this rule. In some cases, the statute of limitations starts when a person discovers or reasonably should have discovered an injury. When dealing with government agencies, SOLs can become even more complex.

For example, special rules may apply if you are pursuing a claim against:

  • A federal employee
  • Someone employed by a military hospital, Veterans Administration facility, or a federally funded medical entity

In these cases, you may need to file a birth injury claim under the Federal Tort Claims Act (FTCA). In FTCA cases, claimants must go through certain administrative procedures before filing a lawsuit. In some states, you may have less time to give notice if:

  • The negligent party was a local or state government hospital
  • The doctors and medical providers are employees of a governmental entity

If you file your case outside of the statute of limitations, the court will typically dismiss it. This means you will not be eligible to recover compensation for you or your child’s injuries.

Determining when a statute of limitations begins on your case can be tricky. If you are considering pursuing compensation for a birth injury, contact an attorney as soon as possible.
