Hello, my son is 27m old. He has about 100+ words/sounds/gestures, lots of words are hard to understand by stranger but I know what he mean and some words are clear. He has some phrases like "where is ball", "here is plane", "I am hungry", "hi dad" etc and some as with his words some phrases are clear and some not. He know whole alphabet, basic colors, numbers up to 12. He can solve puzzles easily (even for 3y+ toddlers). He can point everything I ask him or answer some questions like "what is it", "where it hurts" and following commands ("get your shoes", "bring me the ball") etc. But I watched younger toddler who has full complex conversation with his parent and since that I am concerned but by CDC milestones he is in the range of normal maybe on the lower end. His pediatric doctor is not concerned but I am. Is this in range of normal? Or someone with similar toddler?
