Get rid of Nipple shield

So I had recently put my baby on bottle and formula since I didn’t think she was getting enough booby milk and she would latch for me for awhile.. she a week and a day old, I finally got her to latch with the nipple shield and will continue but how do I get her off the nipple shield and straight to nipple? I had to use a nipple shield too at the hospital cause her tongue kept getting in the way.
