However we cannot say that this is the correct order – that “Pregnancy” applies to the entire period from the beginning of Netzach-Hod-Yesod until their completion while “Suckling” lasts only from the start of Chessed-Gevurah-Tiferet until their completion (i.e. from birth until the conclusion of the first twenty-four months of Suckling), with “Maturity” being from the start of Chochmah-Binah-Daat – at twenty-four months – until their completion at thirteen years.
We cannot define Suckling and Maturity in this way for three reasons: (1) If Maturity is defined as beginning at the conclusion of twenty-four months of Suckling, which is when Chochmah-Binah-Daat start to enter, there would have to be a fourth period after thirteen years, when Chochmah-Binah-Daat are complete. The period of Suckling would then be defined as lasting only for the first twenty-four months and Maturity until thirteen years, while the ensuing period would have to be called by a different name.
