Girls, hi. I have a question. My son is almost 8 months old, he just started sitting (unconfidently), not crawling, not standing on his feet. We've been to doctors, an orthopedist says everything is good. We got a general massage, a neurologist said it's also good but you can drink Elkar 2 times a day, 5 drops each. It seems like everything is good, only one thing bothers me. When I put the baby on his feet and hold him, he doesn't try to walk, he just stands still, doesn't move his legs. Is that normal?
