A teether comprising separate sheets of plastic material sealed together along their edges, said sheets defining separate cells connected by narrow necks, said teether having fluid under pressure in the cells, the necks defining fluid flow paths between the cells; at least one seal set inwardly from the edge seals joins the opposite sheets together at the necks to define multiple flow paths at the necks limiting outward deformation of the plastic at the necks while maintaning a substantial cross-sectional area for fluid communication between cells.
