2 year old not talking

Amanda 😍 • Mama to Jade & Seraphina ❤️1/5/18❤️6/3/19❤️

I'm at a lost. My 2 year old isn't talking. I know she knows things because she can follow instructions and if I ask her to bring me her cup or Sissy's bottle or things like that she does them but she just is refusing to use her words. Her pedi refered her to an early intervention but because she excells in all other categories she doesn't qualify. I'm just frustrated it seems like she's the only 2 year old that doesn't talk. Any advice? TIA
