nipple shield??

Elizabeth
Anyone EBF with a nipple shield? 
They gave it to me in the hospital because I was getting so red and sore, but baby girl has latched so much better with it. (I have flat but not inverted nipples) I'm healed up now and would like to get her off of it but am dreading the work. Breast feeding is already demanding.(literally... on demand) 
Should I just wait till she is older/stronger or will that make it harder for her to switch? 
I haven't touched my pump yet but I heard that can help draw out my nipples.. should I try that first? 
Advice is appreciated.
