Size: Deluxe+ dock vs. Grand dock
The Deluxe+ dock is intended for babies approximately 0-8 months. The Grand dock is approximately 50% longer and wider than the Deluxe+ dock and is intended for tots approximately 9-36 months. Our experience is that parents seem to think their baby has outgrown the Deluxe size before baby is uncomfortable. As your baby grows, unbuckle the Deluxe+ dock to give their legs some room.
