Tommee Tippee Moda 6-18m Orthodontic Silicone Pacifiers 2pcs with an oval, orthodontic shape that vents, meaning it is easier to squeeze than traditional pacifiers, therefore reducing pressure on baby's developing teeth and gums. The symmetrical, soft silicone teat that is fully reversible does not tilt upwards so that the pacifier is always correctly placed in your baby's mouth, even when the baby puts the pacifier in their mouth by themselves.
