My 3 year old just said his first real sentence and it was to me

He looked right at me this morning and said 'Daddy, play trucks with me?' Clear as day. My wife was sleeping so it was just us and honestly I got a little emotional. We've been working on speech with him and his therapist said he was making progress but hearing him actually ask me something independently just hit different. We played trucks for 45 minutes and he was so happy. Best morning ever.
