AITA For Pointing and NOT Talking?

I, a BIG BOY of 18 munts would prefer to point at things than learn words! If I want a toy, I'll just say "UH!!!" and point at it. Same with food (and I LOVE FOOD!!!). Mommy (really old, from the previous century, F) and Daddy (also really old, M) are always stressing words. Like "Oh, do you want Pooh or Tigger?" or "Yogurt or Cheerios?" Don't Mommy or Daddy know what I'm talking about? Shouldn't they know what "UH!!!" means? And why doesn't saying "UH!!!" louder help? Why do they still ask me questions? They seem to understand my sign for MORE and ALL DONE! Why don't they understand "UH!!!?" I can say Mama and Dada...isn't that enough? Why do they want me to speak words? They have been talking about something called "speech delay" and saying that we need to see a "speech fer-a-pus" So fellow babies and toddlers, AITA?

NOTE: This was my son when he was that age. He ended up not speaking in sentences until he was nearly 3. But let's all blame the Pandemic for that.
