Utility is an economic term for a person's overall well-being and satisfaction. Consumers play a role in the economy by maximizing utility, which means allocating their scarce resources, such as limited time or money, most efficiently. Utility maximization is different for every person.
You can start using it right away but it was suggested to us by our midwives to hold off until 6 weeks as pacifier use can mess with their breastfeeding latch (it's a different kind of sucking).
Some of the good things pacifiers can do for your baby -- and you -- include: 1  Lower risk of SIDS. Pacifier use during naps or nighttime can prevent sudden infant death syndrome. 2  Satisfy the suck reflex. Babies have a natural need to suck. 3  Encourage baby to self-soothe.
