Fish Teether is perfect as the first newborn baby toy and also designed for premature babies. Its design allows a very easy grip. It is light and has a thickness that favors grasping, as when the baby holds the fingers of the parents, providing a feeling of protection and security from the first days of the baby's life. The rounded shape favors the baby to join his hands in the midline, encouraging greater body recognition. Its tail has a roughness that helps stimulate and relieve gum discomfort. It was developed by professionals in neuropediatrics, psychology, neuropsychology, speech therapy, and physiotherapy, experts in child development.
