Are you implying that a childless teacher, that has been in the profession for 25 years, has less experience raising children than the parents of a single toddler?
A childless teacher is a pseudo-parent 8-3:30, 5 days a week, 9 months a year. They honestly havent got a clue. They can head home and chill. While parenting is an endless grind.
Kids will wedge into every spare moment and literally consume all the space, physical and mental energy.
Try spending all night up with 3 kids with the stomach flu then having your boss push you to meet a deadline the next day.
These teachers, including my mother in-law can keep their `advice`.
It's apples and oranges. A teacher is not "raising" children; they are teaching them in a controlled environment with certain expectations and structures. Also, a teacher is likely to focus on a certain age group and become expert in working with children in a relatively limited age range. A parent must work with their children over the entire span of their life.
The teacher is not up in the middle of the night with the child when they have strep throat. The teacher is not up in the middle of the night when their child has a nightmare. These are the sorts of things that only happen when you are a parent.

I understand your what you're saying, but this argument works against the argument that parents are automatically qualified by virtue of experience: a mother of a 2-year-old has no experience raising a 3-year-old either.
