Nipple Piercing

it’s been about almost 6 months since i had my nipples pierced. i clean them with antibacterial soap and use sea salt of course there are crustys so i usually soak them with water and clean them up with cotton swabs they have the perfect kind the pointy ones so it really helps to clean it and get everything. anywho i started to use Aquaphor after i clean them and it’s helped a lot i don’t have any puss coming out it doesn’t hurt my boobs aren’t sensitive to touch anymore just the crustys i do have a bump on my nipples of where the bar is from getting hit in my boobs from my 10 month old in the beginning of when i first got it done is there anyway it could be infected ? also is it bad to use aquaphor ?
