With nothing but love, aren't you a tad confused about priorities? You are letting the tail wag the dog.
1) You child wants to go to medical school.
2) In order to get into medical school, she will need excellent grades.
3) To get excellent grades, she will need to study.
4) In order to study, she needs a great deal of time.
5) Softball at the D2 or D1 level will consume a lot of time.
6) She will play softball for 4 years in college.
7) She will be a doctor for 40 years.
You make very good points, however the priorities are 100% academic. She's just looking for possibilities of having both... If it turns out the course load is too much to do both, I'm certain ball will take a back seat.
