Hello everyone) ?. Could you please tell me if you gave your children vitamin D? We've been doing it for a month now, but the pediatrician didn't say anything about vitamin D. I read that it's not necessary in summer, but we don't spend much time outdoors, we don't get much sun exposure, we go for walks in the evening. And if we need to give it, what is the best vitamin D? Thank you ☺️
