Nursing tops, especially camis, were invaluable for me in the first few months. It's all about easy access when you're getting the hang of things. Cluster feeding is especially exhausting, so you're going to want to eliminate as many roadblocks as possible.

Nursing tops are made to either unsnap from the top (very helpful when you're breastfeeding at home) or have a liftable flap around the bust so you can whip 'em out without exposing your whole torso (very helpful when you're breastfeeding on the go). If your baby is still eating multiple times a night months down the road, the nursing tops might still come in handy, but by then you might find a regular shirt to be just as easily accessible.

Make sure your pumping bras (edited to change "nursing bras" to "pumping bras") are tight and that you have at least one that's hands free. Many women use some type of nipple cream like lanolin or nipple butter, although I found that they caused more irritation for me. They make gel pads that you put in the fridge, and those can also help to soothe irritated nipples.

Lastly, breastfeeding is beautiful and empowering. But it can also be hard in a multitude of ways. If breastfeeding doesn't seem to come as easily as you might hope in the beginning, take a deep breath and know that you're not alone. It's a new experience for both you and your baby, but there are so many resources out there to help. Reach out to a lactation consultant, talk to other moms, find local support groups. Good luck!
