Size: Deluxe dock vs. Grand dock
The Deluxe+ dock is intended for babies approximately 0-8 months. The Grand dock is intended for tots approximately 9-36 months. Our experience is that parents seem to think the baby has outgrown the Deluxe size before the baby is uncomfortable. As your baby grows, unbuckle the dock to give their legs some room. Please note that the Grand dock is no longer sold with a buckle.
