A recent study published by researchers at Johns Hopkins University found modest declines in developmental milestones among young children in the United States during the COVID-19 pandemic.
The study, published on April 22 in JAMA Pediatrics, analyzed data from more than 50,000 children, including infants and children up to 5 years of age, to determine whether the pandemic negatively affected their developmental milestones across five domains. These domains included language and communication, problem-solving, gross motor skills, fine motor skills, and personal-social behaviors.
