Using this child carrier is easy. First, make sure your child can sit upright independently as it's suitable for kids around 9 months old. Adjust the shoulder straps and hip fins to fit your body comfortably. Then, gently place your child in the seating area and secure them with the easy - to - use safety harness. You can access the child from the side. You can carry up to 18 kg of the child's weight and 4 kg of baggage. Remember to clean the removable and washable chin pad regularly. Although the carrier is lightweight, don't over - load it with excessive baggage. And since the sun roof and rain cover are not included, you may want to get them separately if needed.
