Coconut oil rubbed on after a shower has really helped mine.
Either a maternity bra or a cotton sports bra without any wires on anything
Mine are the same way even when i go inn the shower the water feels like lasers on them. I'm going to look for a maternity bra.
Lotion has been helping me. Every morning and night. I've also been looking for a maternity bra because that is supposed to way more comfortable, so if you don't have one yet that should definitely be your next step.
