Bright Starts Grab & Stack Blocks is a playtime classic. These four soft blocks have 3D-like crinkle fabrics, satin tags, rattles, jingles and knots, to keep the baby busy building and exploring. Sewn-in loops are perfect for attaching them for on-the-go fun. Each block has a number, letter, character and colourful pattern to engage all of the baby's senses.
