Tattoo'd Mommas!

How long did you wait after LO was born to get another tattoo? I have a huge itch to get another and I just found just came across the perfect one I want to get for my son and was wondering when I would be able to get it. I am planning on breastfeeding if everything goes according to plan but I know if it's a reputable person/ place (which I always go to) it shouldn't really matter? I might be wrong about that. Thank you in advance!
