The Bumbo seat is known as a seat positioner and was created to help babies learn to sit up by themselves and develop good posture. However, physical therapists hate the Bumbo because it does the exact opposite. Babies actually learn to lean forward, curving their backs. This seat
also discourages natural movement.
Moms should instead try to encourage natural play and movement, perhaps placing the baby in between her legs as she sits on the floor with the baby so they can gently lean against their mother and attempt to lean forward and reach for their favorite toy. Keep toys or a favorite token (lovey, blanket, stuffed animal) in front of them so they can experiment with moving their body and strengthen themselves to successfully sit up in their own time.
