DS is 21 months old and has recently started speech therapy through Early Intervention. He has a speech delay and didn't say his first word until about a month ago, but his hearing is fine. Anyways, he has therapy twice a month and then we are supposed to work with him in between. However, I'm kind of conflicted about the instructions the SLP has given us. She wants me to pretty much only do sign language with him and she wants me to sit him down for a minimum of 20 minutes, 3 times a day to work on certain activities (puzzles, sorting blocks, ect) and refuse to let him get up until he has finished the given activity. She wants him to do the signs for "more" and "again" during each activity. Along with a number of other signs. She also expects him to sit still with her for the entire hour of his therapy session and do all of her activities. I just don't understand how she can expect him to sit still like that for so long. He's not even two yet! Also, he has never once even tried to imitate the signs (its been a couple of months of trying now), and me (or the SLP) refusing to give him the next puzzle piece until I've done the sign myself a few times and then done the sign with his hands a few times just makes him upset and angry and even less likely to want to continue sitting there. He does say three words regularly and consistently now, and says a few others sporadically. He also tries to repeat back what I or DH say pretty often too, so I feel like he's getting there and learning to talk. He is also very good at communicating non-verbally by showing us what he wants.
DH and I both just feel that what the SLP expects of him is not realistic or very helpful. I don't think sign language is the right thing for him, and forcing him to sit still that long just doesn't seem right to me either. I want to help him, but I just don't feel like this is the right way to do it. DS is my first child, so maybe I'm totally off track with this and she is right? Is this what speech therapy is supposed to be? What do y'all think? I am definitely planning on talking to the SLP the next time she comes to see what she thinks of it all too, but I'd like y'all's thoughts on it first, please. Thanks.
