Hello Siti Ain definitely you are not alone I faced it and so are most of the mothers. Pls wear maternity bra with pad. Also you can use lanolin cream after pumping or feeding they are safe for babies so it should not be a problem. You can apply coconut oil few minutes before bath. I used Medela nipple cream and Earthmama nipple balm
You can wear as soon as finish latching and pumping. Before feeding and pumping wipe it off first. Yes you need to wear bra specifically nursing bra, loose and with breast pad.
