Hello everyone! Need advice! Yesterday we were at my friend's house, I came with my daughter, she was crying. She doesn't even perceive people except me. It's crazy, I understand. She has always been in a big family, it shouldn't be like this that she cries when seeing people. I don't know really. But so much screaming happened, I even had to blink away, and we left home. I'm tired all the time with the child alone, I want to hire a nanny for at least an hour or two, maybe try leaving her for half an hour, there is a video camera in the apartment, can you say if anyone has such experience?
