Hello everyone! My son has been having such a period for a year now that he doesn't let me go anywhere, as soon as I stand up and want to go somewhere or get out of the room, he starts crying loudly and crawls after me. The husband works in a day and when we are alone with the child, it is difficult because I can't even go to the toilet. I wanted to know how long this period will last and maybe there is some way to help him go through this period?
