3 years & up. It's that time; your baby is reaching the point of no longer needing diapers! Celebrate this point of growth with your baby with the Baby Calin Interactive Toilet. The lid closes and opens, and the flush button features 2 sounds: the baby using the potty and the flushing water. 3 AG13(LR44) batteries are required and included. Ideally sized for baby dolls with a height from 12" - 14". Encourage the development of social and emotional skills. Includes 1 toilet, 3 batteries.
