Girls, I'm at my wit's end! I'm really worried about my daughter, she's almost two years old, and she doesn't want to learn anything. I show her colors, animals, sounds they make, I try reading books, but she just shows no interest. She simply goes away and that's it. Only interested in music, dancing, and drawing. I remember my older son, he knew everything I listed at her age, but he was always smarter than his little ones, so I can't compare him. Mommies, share how your kids were, should I be worried ?
