Super itchy

Kr
So the last few days my nipples have been really itchy and a little dry. Last night my husband and I had sex and when he sucked on my nipples, he said he got the slightest bit of milk out. Any opinions on what I can put on them to help? I bought the baby oil jelly with aloe and vitamin e for my belly, maybe it could help??
I'm 16w4d, 2nd pregnancy. Also, is it possible to start leaking already? With my first, I didn't leak until 24-25 weeks
