I’ve learned from personal experience that suckling is natural, instinctive, something hard-wired into us from birth – it certainly helps to know the basics in advance, but once you actually do it for yourself, your maternal instincts will wake up and guide you.
The first time I ever dry suckled, I was nervous about being unsure how to latch on and suckle properly. I knew the key is to draw the whole nipple into your mouth, so it touches the roof between the rough front and the soft back close to the top of the throat. Once I had done so, I soon found myself suckling away using my tongue in a rhythmic movement, just as if I’d nursed before or always knew how to do it.
