DaasYochid -“Women obtain “da’as” at 12, men at 13.
The fact that women mature faster than men is Halacha L’Moshe Mi’Sinai.”
Daas has nothing to do with maturity. If it did – there would be no Machlokes in the Gemorah when does a girl and boy become Mechuyav in Mitzvos. One Shitta holds -boys at 12 & girls at 13.
