My daughter Mei is five years old, and still her speech is very latent. She makes a lot of noises that sound like speech, but her words are still very unclear. This has us worried because she is about to go to kindergarten, and we re worried about her social health with other kids. She s been going to speech therapy since she was three, but improvement has been very slow. Our three year old son has better speech than her already, and a wide vocabulary.
