How can we understand what babies are crying about? Does their cry sound different when they are hungry compared to when they are tired?

i all abt trial n error.. baby cry when they r hungry diapers wet tired (time to zzz) stomach not well too hot or too cold they way u carry her not comfortable or even when feeding she cry -milk too hot or too cold) urine ( my girl will cry (scream) when she need urine so need carry her to toilet to wee) u have to slowly explore..
