Speech Delay

How do I know if my daughter has speech delay but repeats some words back to me or her dad

My son is almost 21 months and has very little spoken words. I had him evaluated with early intervention and I just heard back that he qualifies for services. It's a little bitter sweet because on the one hand I'm glad he will start speech therapy and that my concerns are being taken seriously but on the other hand it hits a little hard knowing that he is in fact speech delayed. I'm doing the initial family service plan on Friday. Has anyone done this? I'm guessing they will discuss his current developmental milestones more in depth during this meeting.

My son is getting early intervention for his speech and I really wanted to connect with other moms in the same boat, I have friends but they dont want to talk about it and it's frustrating having nobody to talk to about this

I want to start him in early intervention, but he doesn't trust strangers, doesn't want to listen/learn, wants to do life and communicate how he wants to. He acts like, I know you want me to point to what I want, but I'm gonna just yell towards the item I want lol or I know you want me to sign "more," but I would rather just hit the table to indicate that I want more...because it's effective! Does that make sense? It's like he communicates in his own way and it frustrates him that we want him to communicate differently. Doesn't anyone have a strong-willed kid who did well in early intervention/working with speech/behavior professionals? I just don't think it's going to go well. Is it hands-on with the kids or is it more training for parents to learn and apply techniques or whatever?

My oldest is 18 months and still babbles. He doesn’t clearly say any words besides bite, bye, dada. He does say other words that I understand but they’re very mumbly and unclear and he’s obviously not where he needs to be with his speech. There’s not a problem with his understanding, and he points to things he wants or brings me things he wants so communication isn’t the issue. Has anyone else’s little one had to have speech therapy? What should I expect? And does anyone have any little tips or tricks to help with working on speech?
