This may sound dumb

So my almost 2 year old daughters new thing lately is repeating random people’s names even we they are not around.It’s almost like she is checking to see if they are there. She also will say the same word over and over and over until she gets what she wants like a cookie or fruit. I’m never around young kids and there aren’t any kids in my family so I feel like this is strange behavior. PleAse tell me I’m crazy!
