16 month old not talking

Liz

I’m starting to get concerned that my daughter is 16 month old is not saying any words. She only says mamamamama when she’s crying … and she randomly will say dadada . She babbles a lot but doesn’t actually call us mama or dada or ask for baba. I know that speech therapy isn’t the end of the world if she needs it but as a first time mom it’s heart breaking . We do reading , lnarrating, she watches a little bit of miss Rachel every day where she has learned all the gestures to Itsty bitsy spider, the wheels on the bus and even knows a bunch of her body parts . Any advice on how to get my baby to start talking or to get me to stop worrying ???
