Very few first time parents go into parenthood thinking "Ah yes, I hope to give my baby a dummy". The realities of having a baby, just like the reality of childbirth, are often very different to what you expected.
Dummies tap into a baby's natural and normal instinct to gain comfort by suckling. They are used by millions for good reason - the simplest and gentlest no crying sleep solution.
My children have preferred the cherry teat dummies, but every child is different. I have heard lots of others recommend MAM dummies.
You may need to hold the dummy in place to calm a newborn, they don't have strong sucks or jaw muscles, compared to older babies.
