teach my baby sign language

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.

I’m going to start working on this now. I started about a month ago and I think she picked up the sign for milk but then my husband tried to tell me that she was probably just waving. That discouraged me a bit. But I’m going to start again. I was going to take a class, but I think I can just borrow a book and DVD from the library and save some money. Now is a good time because she’s at the point (11 months) where she really wants to express herself but can’t. I want her to learn the following signs: milk, more, food, drink, water, mommmy, daddy, sleep.
