While breastfeeding how do you stop/pause baby latching onto your breast?

Normally, I don't stop my baby when she is latching. In the beginning when she didn't know how to latch properly and it hurt my nipples, I would do what the nurses suggested which was to use my little finger to break the suction between my baby's mouth and breast. Once a bit of air gets in and breaks the suction, your baby will unlatch.
