Hey, I find it hard to explain myself over messages. But my mum took me to a speech therapy course when I was around 11 y/o which went for a week. They made us talk at 60 syllables per minute and then slowly during the week sped it up to normal speed. I found that joining all the letter and words like a train made it easier (so the words flow) But at 3 y/o I’m not too sure tbh, sorry
