An online review of many different child backpacks rated this one #1 and we see why. It is very well made, durable, full featured, adjustable, comfortable, strong, and attractive. It comes in different sizes and just make sure you don't get one that too big for your child. The bottom of the pack should not be lower than your child's lower back, otherwise the load in the pack will strike and/or rub on your child's upper-rear hipbones. Use the chest strap and make sure all straps are adjusted properly. Also make sure the load is evenly distributed and that it does not exceed 10% of your child's weight.
