I use this thing called a Baby Safe Feeder (Sassy also makes a similar product) that has a handle and a little net bag that attaches. YOu can put different stuff inside the bag for the baby to chew on. It doesn't need to be frozen - you can do crackers, meat, etc. But when my baby is teething I freeze fresh fruit (like cantalaupe, peaches, etc) and then put the little cubes into the baggie for her to chew on. It is yummy and it soothes her gums! I got it at Babies R Us on Cooper St. near the Parks Mall.
