Hi moms, can you share when your children started talking? Did they say their first word? My child is 2 years old and doesn't speak or repeat anything. The pediatrician diagnosed it as a speech delay. She prescribed a course of Cortexin. We saw a speech therapist and a defectologist, she said that before 2.5 years old she won't take on classes. Share your experience. Thanks.
