Nipple piercings

Sammi
Hey ladies!
I just got my nipples pierced yesterday and I have no pain at all until bumped or hit accidentally. Just wanted to know how long does it take for them to heal? My pierced said 3-5 weeks but the internet said 6-12 months. Also if anyone has them already, what did use to clean them? My piercer said the solution for ear piercing. And how long till my boyfriend can play with his hands and mouth ? 
So many questions!!! Thanks for the help!
