What Are Delayed Developmental Milestones?

The pediatrician will check for the milestones during regular checkups of the child. If any disability of the child is noticed and if he or she is not achieving any milestones for his or her range, consult a specialist immediately. Conditions such as autism, Down’s syndrome, brain injuries, and any complications during pregnancy can cause developmental delays.

Can a Child Overcome Developmental Delay?

Developmentals disabilities are lifelong, but people can make progress with the help of therapies:

  • Physical Therapy: Physical therapy is usually helpful for children with delays in gross motor skills.

  • Occupational Therapy: Occupational therapy helps to improve daily activities.

  • Speech and Language Therapy: This specialized therapy helps children improve their speech and language.

  • Early Childhood Special Education: Special education is special needs education which is the education of children who differ socially, mentally, or physically from the average to an extent where they require modifications of usual school practices.

  • Behavioral Therapy: Behavior therapy or psychotherapy is used to treat a wide range of behavioral issues.

What Are the Parenting Tips to Prevent Delayed Milestones?

  • Screen time must be zero for children under two years. After two years, it should be limited to one to two hours a day. Too much screen time can lead to trouble sleeping and affects the ability to think.

  • Language skills develop at a very young age, so it is important for the parents to talk with the child often throughout the day.

  • Keep engaging the child throughout the day by singing songs, reading together, storytelling, activities like building blocks, and clay, imitate actions such as clapping, listening to baby sounds, and repeating them.

  • Recognize and acknowledge when a child does correctly.

  • From the age of four to five, many children talk back. Address these behaviors without reacting to the words or behaviors.

  • Children should be tested for autism at 18 months and 24 months. If there is any problem, the doctor will refer to early intervention.


Early childhood development is important and is to be identified, taken into consideration, and one should intervene immediately if there are any developmental delays noticed in a child. Observe the child's growth and development, and if any intervention is required, proper therapies have to be provided. These therapies may not help in treating the condition completely but will surely affect the child's overall development.
