Thumb or Pacifier Babies need to suck, and sometimes feeding isn t enough to meet their sucking needs. Extra sucking on a finger, thumb, fist or pacifier can help baby to calm herself down when she is upset. Finger sucking is natural. Some babies suck their thumbs even before they are born. Most children will stop thumb sucking by themselves by the time they are 5 years old, if no one draws too much attention to it.
Pacifiers can also calm babies.
Babies may prefer a pacifier with a nipple just like his bottle. One-piece pacifiers are safer. Never tie a pacifier around your baby s neck. Don t overuse the pacifier. Try other ways to comfort the baby first, like holding, rocking or singing.
