I have tried teaching sign language to my first born but failed big time because she couldn't do much with fine motors. By the time she could master some skills, she has already started to communicate verbally. She's coming to 3 years old and could barely cope with alphabets. 1. When is the ideal time we can teach our baby sign language? 2. Is there a specific time frame how long each session should last? 3. How do we go about teaching it? I have a guide book and flash cards.
