Mines the same age and still just babbling too! Like someone else commented, I’m going to wait to get nervous till he’s closer to 2.
Has your toddler hit other milestones? If so I wouldn’t worry so much. My friend’s son didn’t say momma or dada till 2 years old and didn’t fully talk until 3. She took him to the doctors because she was concerned and the doctor said he would talk when he was ready and there was nothing to worry about.
16 months is still so young. Try not to stress!! If my kiddo was getting closer to two and still not talking, I'd start to ask questions. Some kiddos just start talking a little later. Continue to read as much as possible anf sing a lot! Talk to her and explain everything she is doing and everything you are doing. I'm sure she will pick it up soon!
