Exersaucer
An exersaucer is a sitting toy for babies and consists of a saucer and a seat where the baby can sit and play with various attached smaller toys. The fear of rolling over or falling is negligible as opposed to baby walker which can roll or tilt because of the wheels. Exersaucers are stationary and contain many little things to keep the baby engaged like teether, colorful soft toys or bells with lights, sounds, and music which help to develop the baby’s vision and hearing senses.
