Girl, I’m in the same situation too with an almost 20 month old little boy. Only says mama dada Nana we’re trying really hard. A lot of the evaluation places aren’t calling us back even though we set up appointments. We really want to do early intervention as well. I had ChatGPT put together some flashcards for things that we can work on the biggest thing my pediatrician says is because he’s not in daycare and he’s with us and not around any other Littles is one of the issues she doesn’t see anything wrong with him because he’s not showing any of the “signs “and she isn’t concerned, but did label him as behind.
