I bought spirulina for my sister. Hopefully the baby can get the benefit from it even though not 100%.
Here is info about spirulina that attract my attention :
“Spirulina contains unusually high amounts of protein, between 55 and 77% by dry weight, depending upon the source. It is a complete protein, containing all essential amino acids, though with reduced amounts of methionine, cysteine, and lysine, as compared to standard proteins such as that from meat, eggs, or milk. It is, however, superior to all standard plant protein, such as that from legumes.”
