Almost 2yo doesn’t speak at Daycare

T

Hi all

My daughter will be 2yo in October , though she speaks few words (mama papa baby nana dada bye hi eye)but few words she speak half like da in duck, do in dog ,no in nose etc,,, but she speaks only in sign language at daycare!!

How to make her speak there? So that she can communicate, also how to improve her vocabulary!!

She lives in duo-lingual home

Please suggest 🙏
