What observations did your family member make?
I would write them down and bring them to the pedicatrician and ask for an OT evaluation. Sometime you can look for a OT who treats children and is knowledge in Sensory Issues and make an appointment directly. Depends on insurance and local custom.
I do think that rethinking your plan for kindy is a good idea, and that testing will help. Would the school do testing now, or does she have to be enrolled. You can always send her to kindy now and do another year if she doesn't seem ready.
Is it a half day kindy or a full day?
Best Wishes,
Grinity
