Hello everyone. I recently worried that my 7-month-old baby isn't crawling and now I worry that he is getting up on his own support too early. Crawling started a week ago and immediately began standing up on his support. He crawls up to the sofa and stands up. Can you tell me if this is too early? Should I consult with doctors? On the internet it says that before 9 months it's bad.
