From tummy time to sensory play, the Play Gym II from Lalo gives babies so much to see and do. The soft, organic cotton mat is adorned with engaging shapes little hands can grab, plus fun surprises like a flip-up mirror, squeaker flap and object-permanence pocket. As babies sit up, they'll love discovering colorful teethers, a bell and a play panel designed to keep infants busy as they develop sensory awareness and motor skills. Plus, the wooden frame assembles and collapses without tools, so it's easy to keep the good times going from room to room.
