Hmmm I couldn't say, as I only was able to identify mine in general, and they were ascaris. I never looked at them that closely. Mine were not exactly white, but kind of pink/grayish. I just hope they go away forever for your family! I can so identify with the angst over your child. We do our very best to give them the best start, and then stuff happens. Hugs!!! You are doing a good job!
