Teether
Haakaa Rosie Rocking Horse Silicone Teether
A teether that is also a rocking toy, in food-grade silicone, with different textures on the head, tail and body so a baby can find the one that works on the day. $23.99 is on the high side for a teether, and the honest caveat is that no teether is guaranteed to be the one your baby accepts.
