Repeating words out loud -3 year old

My 3 year old will repeat over and over when she’s hungry, thirsty, in pain etc. I notice that I do the same thing when I have physical pain or I am tired or hungry. Did I create this? Is this a way to deal with uncomfortable feelings? I’m generally someone who lives in my head so complaining out loud seems like a strange way for me to cope or maybe Im resisting. Thoughts on this?
