We recommend 10 to 15 minutes a day, at least an hour before bedtime! We advise you to have fun and look for the activities they like to do! If your child is just starting to talk, this experimenting can be very useful. We usually advise progressing through the exercises (as a flow) from top to bottom, but also realize that their choice will determine how engaged they are from the beginning. Before starting a section, ask questions about what they think they will see.
