I hope that helps, seizure disorder is not a good thing to have to deal with. I think we’ve discussed that on the Travolta thread IIRC. Do you do a lot of sunscreen? It can block D as well.
I let the kids go to school without sunscreen except when it is really hot and sunny (May, August). They eat outside, PE, and breaks outside.
In the summer, it’s sunscreen all the time.
I’m making sure my other 2 kids are getting vitamin d supplements also because I’m worried about them not getting enough vitamin d.
