How do you deal with toddler tantrums?

I am a working mum. Nanny is taking care of my baby son. He is very quiet when I am out of the home. But in the evening and during holidays, he used to bother me. and also cry always. When we are out of the home. he still crying and asking to do some other things which can not be done at that moment. Maybe he missed me in the daytime. Do you mummies have experiences with this? Can anyone advise me
