Girls, how many words does your baby speak in our age range? Mine can barely say "Mama" and that's not every day. Sometimes only. And then it explains with sounds, "uh-huh" or "u" ??‍♀️ But she understands. She brings things when I tell her to bring them. But sometimes doesn't respond to her name, she does this on purpose ? When she wants to turn around, when she doesn't want to, no. Afraid of people, especially doesn't play with kids. Also afraid of sharp sounds. About words, I'm very worried.
