When I look after my neice which I do about once a month or so, when her parents leave she absolutely screams bloody murder for like up to 5 minutes. Is this normal? She is 3.5 years old. I end up just leaving her as I offer drink, toys, but anything I offer makes her scream more and the closer I go to her the more she screams so I just say I love you and I'm here when you're ready. I tried just sitting with her but that makes her scream more. Am I doing the right things?
