A screw-on spoon now allows caregivers to feed babies from a pouch with one hand. Plum Organics Inc., part of the Nest Collective, has introduced a plastic spoon that screws onto the fitment of a Plum Baby Food pouch. The caregiver squeezes the pouch’s content into the spoon’s bowl and can feed the baby with the same hand. The spoon is trade-named Spoon by Boon, after the firm that helped design it, Boon Inc.
