I would say that her children's musical abilities have nothing to do with absolute pitch and everything to do with having a super smart, well organised and consistent mother. Their earliest memories are of bonding with the world's most important person over music, almost every day of their lives. They speak 3 languages, they talk with their friends about synethsesia, etc. They're a family of absolute brain boxes. So I think following this method with your toddlers will probably recreate musical ability, and absolute pitch, but following a different musical routine with this level of regularity and consistency would also recreate the musical ability.
