The Special Delivery Baby Hammock is designed specifically for newborns and babies up to 12 to 18 months of age, or when you realize that your little one would appreciate more spaciousness. (Then it is time to move up to the Toddler Hammock which will serve them until they are 4 to 5 years of age.) This is simply the very best bed for your new baby, as they transition into the world. The Special Delivery Baby Hammock maintains the primary curve of the spine supporting your baby with the gentle contours of the hammock, rather than the more rigid, flat surfaces of the typical crib or bassinet. After 4–6 months, if they are able to turn over and are beginning to crawl, you may still use the hammock under direct supervision. Your baby will love the hammock and the gentle motion it offers. Once your baby is able to roll over and crawl, of course it is imperative that you are present when he or she stirs and awakens, to prevent your baby from attempting to get out of the hammock alone. A baby or small child may continue to sleep in the hammock until they grow to be too big for it, which will come long before their weight surpasses the working load of the spring (85 pounds).
