We absolutely love activity mats that can grow with a child, and we were thrilled to check out this PLAYSKOOL Gloworld Music & Lights Play Mat! The activity center includes seven toys that can be repositioned for over head discoveries, tummy time, or sit-up play. The mat also features a glowing sun that provides up to twenty minutes of cheerful songs or comforting nature sounds with adjustable volume. Available exclusively at Babies R Us and BabiesRUs.com. $59.99. Added plus: it reminds us of the Gloworms we loved as a child!
