The primary aim of weaning is to gradually replace natural protein from breast milk or standard infant formula with solids containing equivalent phenylalanine (Phe). In addition, a Phe-free second stage L-amino acid supplement is usually recommended from around 6 months to replace Phe-free infant formula. Our aim was to assess different weaning approaches used by health professionals across Europe.engPhe-free infant formulaPhenylalaninePhenylketonuriaWeaningInfant;HDE PEDjournal article10.1016/j.ymgmr.2018.11.003
