Hello ? Girls, could you please tell me how many days now the baby has been crawling for the third day and rocking? How long will she keep doing this before she starts crawling? When she stretches towards toys with her hands and feet, she lowers them and pushes off with her feet, hitting her face against the blanket. We're almost 7 months old, and she still doesn't have any teeth ?
