Our cards are perfect for early intervention for newborns aged 0 to 4 months. By showing the cards at intervals of 20 to 30 centimeters, the baby's eyesight is playfully trained and helps them focus for the first time. At the same time, interaction between parent and child promotes attachment. The cards are also ideal for interaction between siblings and babies under adult supervision. Enjoy your baby's big eyes and see them learn and grow through visual stimulation! The cards include a penguin, turtle, duck, bear, cat, elephant, bee, dinosaur, butterfly, fish, dog and a frog.
