Shina song bathtub is specially designed for babies aged 0-12 months, so it won't be very big. You can refer to this mother to record the video of using small Shina song bathtub for his baby within one year old. There is no way to take a bath for the baby alone in the big bathtub, so please consider carefully before buying it. The upgraded logo is different from the old one on the writing body. They are all genuine. You can rest assured to buy it.
