My daughter is 3 year old. She says ABC, animals, fruits, veg names, etc. But when we talk to her in sentences, we are ask her to say, she says the last word. She knows what we are saying to her but she doesn't speak to us in 2-3 words or sentences. She is super active child. When we teach her something, she picks up fast. But she is not talking as we normally interact with each other. Concerned abt her ??
