The American Academy of Pediatrics, with funding from the Centers for Disease Control and Prevention, studied the CDC’s “Learn the Signs. Act Early” developmental surveillance milestones for children 0-5 years to update the milestones based on published studies. The goal was to improve this tool for developmental surveillance and use by the public. Developmental surveillance is not just observing a child at a check-up but rather “is a longitudinal process that involves eliciting concerns, taking a developmental history based on milestone attainment, observing milestones and other behaviors, examining the child, and applying clinical judgment during health supervision visits (HSVs).”1
While the milestones we were trained on were a good start and highlighted the developmental progression central to pediatrics, they were not based on norms or cut scores indicating significant developmental risk unless taught from a validated tool. The CDC was concerned that their public handouts and apps were based on median ages (middle number of the entire range) of attainment not the mode (most common) or even average ages. That means that about half of all typically developing children would “not have attained” that skill at the age noted, potentially evoking unnecessary concern for parents and a “wait-and-see” message from a knowledgeable provider who realized the statistical meaning and the broad range of normal. Another potential problem with using milestones set at the median age is that parents, especially those with several children or experienced friends, may see the provider as an alarmist when they have seen great variation in children who later were normal. This reaction can dampen provider willingness to discuss development or even to screen with validated tools. We have learned the hard way from COVID-19 that it is difficult to convey concepts of risk effectively both balancing fear and stimulating action.
The AAP experts reviewed the English literature for data-based milestones, finding 34 articles, 10 of which had an opinion for at least one milestone. If this sounds like a very small number, you are correct. You may not realize that almost all screening and diagnostic tools have been based on data collected by Gesell in 1928!2 While most of health care has changed since then, which milestones are measured in infants has not.
The biggest change from this review was deciding to use as milestones skills reported for 75% of children at each age of typical HSVs, adding ones for 15 and 30 months. The implication is that children not attaining these milestones are all at risk and deserving of more careful history, examination, and administration of a validated screening tool; not true when based on median data. Of the 94 existing CDC milestones retained after the review, one-third were moved to a different age with 21 of 31 assigned to an older age. Domains of functioning for the milestones were consolidated into social emotional, cognitive, language/communication, and motor, to help parents learn to distinguish these areas, and, although many milestones reflect several domains, each was included only once to reduce confusion.
Psychosocial assessment is recommended by the AAP and Bright Futures at every HSV but the fewest milestones with normative data were identified for this domain, often self-help rather than social engagement or emotion regulation skills. The cross-cultural study cited for many of the new milestones was reassuring overall in that the median ages for 67%-88% of milestones in most domains were equivalent across the four countries sampled, but only 22% of self-help skills were equivalent.3 This should remind us that parenting has more influence over psychosocial skills than other domains. Psychosocial and behavioral functioning, especially emotional regulation, also deserve “surveillance” as they have enormous impact on life outcomes but need to be measured and supported differently. Routine use of validated tools such as the Early Childhood Screening Assessment or the Ages & Stages Questionnaires: Social-Emotional for these domains are also needed.
Normal variations in temperament and patterns of attachment can affect many milestones including courage for walking, exploration, social engagement, and prosocial behaviors or self-control for social situations, attention, range of affect, and cooperation. All of these skills are among the 42 total (14 new) social-emotional milestones for 0- to 5-year-olds. Variations in these functions are at the root of the most common “challenging behaviors” in our studies in primary care. They are also the most vulnerable to suboptimal parent-child relationships, adverse childhood experiences, and social determinants of health.
As primary care providers, we not only need to detect children at risk for developmental problems but also promote and celebrate developmental progress. I hope that changing the threshold for concern to 75% will allow for a more positive review with the family (as fewer will be flagged as at risk) and chance to congratulate parents on all that is going well. But I also hope the change will not make us overlook parenting challenges, often from the psychosocial milestones most amenable to our guidance and support.
Early identification is mainly important to obtain the early intervention shown to improve outcomes. However, less than 25% of children with delays or disabilities receive early intervention before age 3 and most with emotional, behavioral, and developmental conditions, other than autism spectrum disorder, not before age 5. Since early intervention services are freely available in all states, we also need to do better at getting children to this care.
Let’s reconsider the process of developmental surveillance in this light of delayed referral: “Eliciting concerns” is key as parents have been shown to be usually correct in their worries. Listening to how they express the concerns can help you connect their specific issues when discussing reasons for referral. While most parent “recall of past milestones” is not accurate, current milestones reported are; thus, the need to have the new more accurate norms for all ages for comparison. When we make observations of a child’s abilities and behaviors ourselves we may not only pick up on issues missed by the parent, but will be more convincing in conveying the need for referral when indicated. When we “examine” the child we can use our professional skills to determine the very important risk factor of the quality of how a skill is performed, not just that it is. The recommended “use of validated screening tools” when the new milestones are not met give us an objective tool to share with parents, more confidence in when referral is warranted, which we will convey to parents (and perhaps skeptical relatives), and baseline documentation from which we can “track” referrals, progress, and, hopefully, better outcomes.
