Baby Feeding Bottle With Spoon As your child grows, nursing and formula may not be enough. When your baby is ready to begin solid foods, but not yet ready for the spoon, the Sassy Baby Food Nurser will help to make the transition. The unique design of this nurser allows your infant to eat cereal through a nipple. The vacuum disk keeps air out and moves cereal consistently without clogging. Baby will feel more satisfied, and you'll know he's getting the nutrition he needs.
