Babies and young children don't typically misbehave deliberately.
By using redirection, you are showing your baby what
Situation: Child is throwing blocks. Reaction: "No throwing blocks. Throw Nerf balls." Then play Nerf balls for a little while. Nerf ball throwing may become a favorite pastime.
Situation: The baby just learning to use a spoon may like to throw food with it. Reaction: Maybe it would be fun to feed Mommy instead? Or feed a toy animal with an empty bowl, taking turns to practice self-feeding. "Let's feed Baby. Feed Mommy. Feed Bear. Not the floor."
Situation: A baby banging a spoon on a pot or high chair tray might trade for a kitchen tool with a sponge top. Reaction: "Too loud. This sounds nice." We need to redirect them to acceptable sounds, or help them use their hearing aids more efficiently. Remember that babies who are deaf or hard of hearing may make noises that are too loud for us, but are just right for them. Babies who are deaf may vocalize too loudly as well. You can model calm vocalizations while playing with toys.
