When is it that I should start teaching my baby? That is a question that may come to mind for many first time parents; other parents may never consider the question at all, and just leave things to evolve naturally.In a way, that is an unnecessary question as, whether you like it or not and whether you mean to or not, you begin teaching your baby while it is still in the womb, and then continue through its early years, teenage years, and even into adulthood. So, perhaps it is better to rephrase .
