Citing from the article: "...Since 2011, 1224 cognitive assessments were collected from 672 healthy, full-term, and neurotypically-developing children between 3 months to 3 years of age. Repeated measures were separated by at least 1 year (mean = 384 +/- 41 days). A general overview of all child assessment timings are shown in Figure 1a. This dataset included 1070 assessments (from 605 children) prior to March 2020; 154 assessments (from 118 children) between March 2020 and June 2021; with 39 children who were born just prior to the pandemic in 2018 and 2019, and following during the pandemic to 2021..."

The age of the kids 'born during pandemic' in this context is up to 18months, not clear how many in count, but total is 39 born from 2018 to 2021. Pandemic start considered March 2020. P.S.

When young children refuse to attempt test items it can be difficult to determine their current level of functioning..."
