Any time a child does something odd on only one side of the body, I always recommend to have it checked out. It may be nothing, and she might grow out of it, but it's definitely good to have someone monitor it to make sure it stops. There may be a tight muscle somewhere that is making it difficult for her to use her left toes properly. If so, it could be very easy to fix the issue. A lot of pediatricians aren't really great at treating walking problems. My suggestion is to try to get a referral to a physical therapist who specializes in children. My guess is you may have to look in Huntsville or even UAB to find one. It might help to ease your mind to have a specialist tell you it's nothing. Good for you for being concerned!
