Iordanis "Danis" Konstantilakis is a dad of two (a 9-year-old boy and a 5-year-old girl) and the founder of Newborn Stages. He has been reading and writing about baby and toddler development since 2016, and started this site in 2020 to give new parents the clear answers he couldn't find at 2am. By day he builds websites at weDigitalPLUS.
He's a parent, not a doctor: every health article here is checked against the AAP, CDC, NHS and other trusted medical sources, linked in the article, and re-checked when guidance changes.
