The Baby Jack & Co. Crinkle Tag Square is the perfect stroller / tummy time toy that will engage and help with stimulation. As a child grows up, the patterns will encourage little ones to learn basic shapes and colors. This 8x8 square is accented with coordinating ribbons that are sewn shut, so little fingers do not get intertwined in the ribbon loops. The variety of textured ribbons and fabrics encourage tactile play and help children develop cognitively, socially and emotionally through sensory interaction. Each 8x8 square has crinkle crackling fabric inside for extra sensory sounds! Each Baby Jack Crinkle Tag Square comes with a toy link to clip onto strollers, car seats, or baby carriers. Since we care about the health of your children, we make our toy links non-toxic and BPA-free. The top fabric is a durable, micro polyester, paired with a minky plush fleece textured backing.
