Part of the Boppy Sideline Collection, the Tummy Time features the Sideline toy adjustment system so toys can be perfectly placed, moved and played with to encourage baby to have longer and more active tummy time. And these connected toys give moms and dads the ability have interact with baby while he’s doing tummy time. Since the toys are connected to the Sideline system, you don’t have to worry about losing or misplacing them. The mini Boppy Pillow is the perfect size for tummy propping and includes two developmental toys.
