The Thinkbaby Sippy Cup easily earns top marks from reviewers focusing on eco-friendly products. Designed with a soft, silicone spout that feels similar to a nipple, babies more readily accept the Thinkbaby Sippy Cup when first transitioning from the bottle, reviews say. The handles are removable, although parents say babies grasp the cup easily with and without the handles. There are some complaints of leaking cups, which seems to occur more frequently when the handles are attached. Parents also say that the Thinkbaby Sippy Cups do not have a vacuum-control device, so the spout tends to collapse while a child is trying to drink from the cup. Thinkbaby Sippy Cups are on the expensive side, but parents who have been using Thinkbaby Bottles may purchase a less expensive conversion kit (*Est. $7 per kit) which includes one set of handles and two silicone spouts) to convert their bottles into sippy cups. For babies who have already transitioned from a bottle, the Playtex Insulator Cup (*Est. $5) rarely leaks, has insulated walls to maintain cooler beverages and costs about half as much as the Thinkbaby Sippy Cup.
