That's exactly what I had to do. I had tried the pin and poked several holes in it but that still didn't seem to be working. So a small X helped out a whole lot. But, keep an eye on the end too before feeding, if the little flaps look like they are starting to be really flimsy or might tear off, make sure you get a new nipple so that it doesn't come off while the baby is eatting.
