It is hard to say this but a baby usually cries a lot when you first leave her, but for the next 20 minutes she should stop if the person is not a stranger like daddy or grandparents. This is the hard part, the babymight not lke them because there might be something going on that you don't know about,that the baby don't like. So be suspicious of anything, seek help from a doctor or social worker which knows a lot about child development to help you deal with the problem. Be carefull you are the only person that baby trust.
