My daughter is now 22 months and she knows signs but doesn’t necessarily use them consistently. Usually she will only use them when prompted. She knows: more, milk, water, eat, all done. She still gets really frustrated by not being to express herself. I’m trying to transition her into using more of her words, because she still doesn’t use many words (she says hi, bye, all done, eyes, me). She sees a speech therapist to work on her speech. I’m planning on just reinforcing the signs she already knows and continue to work on her verbal speech.
