What Am I Doing Wrong?

My boy went to speech today.  His SLP tells me about the language she got out of him that day and I can't help but feel jealous - so incredibly jealous that she gets to hear that.  He's pairing words for her that he's not doing for me.  I ask her what she says - what she does - to illicit it.

I go home; I replicate it, word-for-word.  I incorporate it into our Floortime.  I work so hard to get more than just single words and "more"/"all-done" combos.  Nothing.  I prompt him to elaborate in the way she says that worked for her - "Jack, tell me more!" - and he only responds by echoing back "more".

At school, they get the same thing - single words.  "More"/"all-done" combos.  In a way, that makes me feel better, because it's not just me.  I know that other therapists don't illicit this from him, either.  Still, though, it makes me feel like I'm not doing enough.  It's a dreaded beast that I do battle with daily.  Am I doing enough for my boy?  Do I fight enough for him?  Do I work hard enough?  Am I providing every opportunity for him?

What am I doing wrong?

Please tell me that I'm not the only one who feels this way.  Say I'm not the only one who hears great things from therapists, or teachers, or anyone, only to struggle to duplicate it at home.

In my mind, I try to justify it.  He's in a sensory gym doing sensory-motor activities.  He's given models.  He's given prompts.  He's in an ideal 1-to-1 situation with a trusted therapist.

Why can't I be that trusted person?  Why can't he feel so at ease here with me to get it?  It makes me feel inadequate.

So - that's it, short and sweet.  I put it out there, put voice to it, because I'm hoping that I'm not the only person who feels this way.  If I'm not, maybe I can help someone else feel like they're not alone in feeling this inadequacy and maybe I won't feel quite as alone myself.
