While "mama" and "dada" are very common first words, babies may also say things like:
* "ba-ba" or "da-da" (early sounds they can easily make)
* "uh-oh" or "bye-bye" (sounds they associate with specific actions)
* "no" or "more" (simple words with clear meanings)
It's important to remember that babies learn to talk gradually, starting with babbling and then moving on to single words, phrases, and eventually full sentences.
