Nipples for breastfeeding ?

I’m 28 weeks pregnant

Today my mom asked to see my nipple (we’re pretty comfortable idk if that’s weird for some)

because she wanted to see how it would work for me for breastfeeding. When she saw my nipple she said I don’t have much nipple and it will be hard for my son to latch on. But when I look at my nipple it doesn’t look like it would be hard? I have fairly large nipples since I have large breast about 38DD. Do my nipples have to look/ be a certain way for breastfeeding to be easier? I just thought the only trouble I would have is if my son himself couldn’t latch on for other reasons not because I don’t have “much nipple” if that makes sense? It’s my first born so I have no clue what I’m doing lol
