Frustrated

My son is 18 months today and has a speech delay. He’ll only say mama and dada. Occasionally will say Bubba and Bye bye. He’s lost a lot of words. He used to say all of that frequently and no, Kitty, Pooh, Pinky(cats name) and Booboo(Dogs name) but he just stopped all together for months. About a month ago he started saying mama and dada again and has said Bubba and bye bye like twice. He doesn’t respond to his name and he doesn’t point at things that he wants or to get our attention. He doesn’t understand simple tasks either. Everything else seems to be on track. Everyone around me has told me it’s normal and there’s nothing to worry about and even online. But then I see videos read articles about all the things I listed being signs of autism. I’ve really really been trying to work with him. But it just seems like he’s in his own little world most of the time. His 18 month old check up is coming up and I’m stressing about it. I just don’t know what to do to help him. Everything I try, he ignores. He has no interest what so ever. But everyone just keeps telling me he’s fine. Even though his doctor at his last checkup told me he should be saying at least 10 words by now. It’s just so frustrating because Idk what to do or how to help. I never had to worry about this with my oldest. But he was also in daycare around other kids and older kids talking. My youngest was born at the beginning of the pandemic and has been home with me his whole life. He doesn’t get a lot of social interaction. Just family. I keep wondering if that has a lot to do with it. But then I also feel like I haven’t done enough. I haven’t worked with him enough, played with him enough, let him watch too much tv, etc. My oldest also isn’t doing too well in school and is getting evaluated for ADHD. I just feel like a failure right now and like I have no control over anything. Everything is just out of my hands.
