A child just learning to talk often uses one word to mean several different things.
Real words are words that mean only one thing.
Even if baby says no and shakes his head back and forth, he may not know what the word means. He may even say no when he really means yes. Don t take all his no s too seriously. If baby began to pull up to standing last month, he will probably learn how to get down all by himself soon. He may be fascinated by stairs.
