I use these when my toddler son be teethe as a infant , and I buy a new set that I have be use with my infant daughter . both love they . the bumpy texture be total genious , and -lrb- despite direction to the contrary -rrb- , I have put these in the freezer and with that extra touch these go over even more famously . highly recommend . Great for a new mom 's baby shower goodie bag .
