Researchers and policymakers consider the first 1,000 days after conception critical for the child's ability to grow, learn, and thrive.
“We focus on this phase because researchers and policymakers alike consider the first 1,000 days after conception critical for the child’s ability to grow, learn, and thrive (e.g., Berg, 2016; https://thousanddays.org; https://publications.parliament.uk/pa/cm201719/cmselect/cmhealth/1496/1496.pdf).”
From Birth of a Father: Fathering in the First 1,000 Days (2019) · cites this paper as Berg, 2016
The Editorial describes UK and South African policy initiatives focused on the first 1,000 days, and the Infant observation section calls the first three years of life the most important phase for growth and development. This supports the broad claim that researchers and policymakers regard early development as critical, but the copy does not define the 1,000-day period as beginning at conception. (LLM, conf=0.82)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
