I'm with the others - this sounds like a bit of an exaggerated fib imo.
I gave Gabby a dummy on day two but that was my choice - the hospital doesn't have them on hand. When I asked my midwife about it, she said it was my decision. She said that other nurses had differing opinions but hers was that dummies were good to encourage the sucking reflex. I got Neil to bring one in from home that day because all Gabby wanted to do was suck! She still has one for her day time naps and for when we go out (if she gets unsettled, it helps to calm her down a little).
