Is it okay to leave a sleeping baby at home while you run out for a quick errand nearby?

Its a No No for me. Anytime baby may wake up and if cant find anyone, LO will feel insecure, panic and cry. For LO that is able to stand, climb or even walk even more unsafe as you dont know what he/she may do. Sometimes LO will do somethibg beyond your imagination. Its always better to have at least someone at home.
