M.P.
You describe all the reasons to take her to an optometrist. I wonder why you hesitate.
Are you financially able to take your daughter for yearly well child appointments? Do you have insurance?
If money is an issue, you can take her to a county clinic. THEY charge using a sliding scale. In Portland, there are clinics for people without insurance. You can find affordable clinics on county Internet site. YOU can find others by googling low cost medical clinics
