Indispensable amino acids (IAA) reference pattern for infants and children derived from mother’s milk composition and calculated by the factorial method for young children 1–2.9 years in comparison to adults [27,32].

	Average Protein Requirement	IAA Reference Pattern (mg/g Protein)
	g/kg/day	His	Ile	Leu	Lys	SAA	AAA	Thr	Trp	Val
