Case Study: Using Milestones to Identify Developmental Delays

Developmental monitoring is continuous, ongoing engagement by all early childhood professionals that involves families as experts on their children. It includes eliciting parent concerns, maintaining developmental history, making observations, documenting, and sharing information—but does NOT provide risk scores. Developmental screening uses validated tools like Ages and Stages or M-CHAT that have been studied against diagnostic evaluations to determine sensitivities and specificities. Research shows that when used alone, monitoring leads to 3% of families accessing early intervention, screening alone leads to 4%, but combining both approaches ALMOST DOUBLES the rate of families seeking appropriate services.

Developmental monitoring is a public health communication tool accessible to all community members (parents, teachers, healthcare workers) that identifies when children are not meeting developmental milestones, while developmental screening is a specialized assessment conducted by trained professionals using validated tools to determine if a child falls below their same-age peers; both approaches should be combined for optimal early identification of developmental delays, as the CDC estimates that over half of children who need services are currently not receiving them.

Developmental monitoring is a continuous process where providers observe and track children's developmental milestones (skills most children achieve by certain ages in play, learning, speaking, acting, and moving) to celebrate progress and identify potential concerns, while developmental screening is a formal assessment conducted by trained professionals using standardized tools at specific ages (9, 18, 30 months, and 18-24 months for autism), and combining both approaches with open conversations with families helps ensure children receive necessary supports and services early.

Developmental monitoring is an ongoing process that anyone in the community (parents, teachers, librarians) can perform using free tools like the CDC's Learn the Signs. Act Early checklists, while developmental screening is a formal process conducted by trained professionals using validated tools. The CDC updated its developmental monitoring checklists in 2019 to increase clarity, reduce the 'wait and see' approach, and increase referrals by moving milestones from the 50th to 75th percentile. Combining developmental monitoring with screening is the most effective approach to identify children with developmental delays early, as research shows that one dollar spent in preschool saves eight dollars later in special education.

Developmental monitoring exists on a spectrum from informal surveillance to formal assessment. Surveillance involves casual parent-provider conversations about observed behaviors. Screening uses validated tools to identify potential delays. Assessment employs standardized protocols to quantify developmental status. Healthcare providers can integrate brief developmental checks into routine visits without significantly extending appointment time.

The early intervention process follows a systematic sequence: referral by community sources (childcare facilities, Early Head Start, Easter Seals, physicians, hospitals, and parents), evaluation/assessment for eligibility, eligibility determination, IFSP development, service implementation, periodic reviews, and transition planning. Congress mandated strict timelines: referrals must occur within seven calendar days of identifying potential need, and evaluations must be completed within 45 calendar days of referral receipt. The Individualized Family Service Plan (IFSP) is a written blueprint containing child development levels, family resources, goals, services, locations, payment info, and transition steps. Key team members include parents (essential participants), service coordinator (case manager), evaluators, and service providers. Parents must provide written consent before services begin, and their input must be considered throughout the process.

Early intervention referral is a process that connects families of young children (birth to three years) with developmental concerns to appropriate services. The process involves: (1) making a referral through online portals or local single points of entry, (2) completing an evaluation to determine eligibility based on developmental delays in five domains (adaptive, cognitive, communicative, motor, social-emotional), and (3) developing an Individualized Family Service Plan (IFSP) to support the child's active participation in daily routines. Early intervention programs are family-centered systems guided by federal regulations (IDEA Part C) and aim to enable children to actively engage in their natural learning environments while supporting families in promoting their child's development.

The Individualized Family Service Plan (IFSP) is a written roadmap for providing early intervention services to infants and toddlers with disabilities (ages birth-2) under Missouri's First Steps program, which meets IDEA Part C requirements; it is developed jointly by the family and qualified personnel, includes child's present level of development, family concerns and priorities, measurable outcomes with timelines, specific services in natural environments, and transition planning, with meetings held within 45 days of eligibility determination and reviewed every six months, requiring parental consent for services and providing parents with procedural safeguards to advocate effectively for their children.

Early intervention is a federally mandated service system under Part C of IDEA serving infants and toddlers (birth to 3 years) with disabilities or developmental delays and their families. Louisiana's Early Steps program provides services in natural environments like homes and childcare centers, focusing on developing physical, cognitive, communication, social-emotional, and self-help skills. Access requires contacting the regional System Point of Entry (SPO) to request evaluation under Part C of IDEA. The evaluation process involves multidisciplinary professionals assessing developmental domains including speech-language, physical, hearing, and vision. Written parental consent is required before evaluation. If eligible, an Individualized Family Service Plan (IFSP) is developed within a critical 45-calendar-day timeline. The IFSP requires a multidisciplinary team including parents, advocates, intake coordinators, Family Support Coordinators, assessment specialists, and Early Intervention Consultants. Section 1 contains child information and IFSP history. Section 2 documents family concerns organized by priority across five developmental domains: physical, cognitive, communication, social-emotional, and adaptive. Section 3 provides present levels of physical development including vision, hearing, and health status, while Section 3B uses the Battelle Developmental Inventory (BDI-2) test results to assess cognitive, communication, social-emotional, adaptive, and physical development domains. Section 4 documents measurable outcomes and goals specifying current functional levels, success criteria, timelines (3-6 months), strategies, practice settings, and progress measurement methods. Section 5 addresses transition planning beginning around 24 months. Section 6 documents specific services with outcome goals, locations, frequencies, dates, delivery methods, funding sources, and providers. Parents must receive three calendar days to review the complete plan before signing consent, after which services (except support coordination) may begin.

This section details the Early On (Part C) process for children birth to 3 years. After referral, a service coordinator must be appointed, and a notice for evaluation consent must be sent within 10 calendar days. The Individualized Family Service Plan (IFSP) is written specifically for the child's and family's unique needs, focusing on family outcomes and desired changes. The plan details who provides services, where, when, how often, and what services will be provided. It is a living document that can be changed as needs change. Build Up Michigan provides IDEA-funded support for preschool-age children (3-5 years).

This segment illustrates the transition from baby to toddler stage, covering key developmental milestones such as learning to walk, increased mobility, and the need for more complex care routines. The video demonstrates how toddlers have different needs than infants, including more frequent diaper changes, more demanding food preferences, and the need for structured daily routines including bathing, feeding, and playtime.

This video demonstrates how parents can adapt daily routines to support a 2-year-old's developmental transition, including transitioning from bottle to cup feeding, encouraging independent tooth brushing, and maintaining consistent meal schedules while accommodating the child's changing needs and preferences.

This comprehensive segment covers a toddler's daily life including morning routines, meal preparation participation, and food learning. The toddler learns to whisk eggs, cut food, and classify fruits from vegetables. The segment demonstrates healthy snacking strategies like hiding vegetables in foods children enjoy (spinach and carrots in banana bread muffins). It also covers toddler sleep patterns, developmental leaps causing sleep regressions, and the controlled crying sleep training method where parents allow crying for seven minutes before providing comfort. The Wonder Weeks app is recommended for tracking developmental patterns.

Successful toddler mealtime requires flexibility and adaptation. When toddlers refuse high chairs, parents can eat at the living room table or use a toddler table. The focus should be on getting the child to eat rather than strict adherence to traditional settings. During mealtime, parents can use background TV to keep toddlers engaged. For breakfast, offer simple foods like toast, butter, strawberries, cheese sticks, and yogurt pouches. The key is following the child's lead and being flexible with mealtime locations and foods.

Toddlers develop through structured daily routines that support physical and cognitive growth. Adjustable learning furniture like multi-stage activity tables supports developmental progression by providing appropriate height and stability. Children naturally explore their environment through hands-on discovery, which requires parental supervision for safety. Sleep patterns typically include approximately 1.5 hours of daytime nap time, often between 11 AM and 12 PM. Establishing consistent routines helps regulate circadian rhythms and supports healthy development.
