Wonder Weeks scored 52/100 in our 2026 review. The underlying study (van de Rijt & Plooij) has not replicated independently. Wermom uses CDC Milestone Tracker as its baseline, which is freely available and ASQ-aligned. We recommend Pathways or Wermom if you want milestone data without the leap predictions.
