I dont think it will make a difference before hand but you can always try it!! I had trouble in the first couple of weeks with my DD and a midwife told me to express breast milk onto your nipple and rub it in several times a day, and when using the lansinoh to not rub that in but apply it to the cracks in your nipple, more like packing it really. I would do both after every feed. This worked excellently for me
Hope that helps you, good luck!!
