It's not a dumb question! It shows you are concerned about your child's health and safety! But I would be more concerned about your tanning in general (whether or not you are breastfeeding) and wanting to actually be around for your children as they grow up; skin cancer is very serious and deadly and I wouldn't tan for that reason. Plus I love the super-pale look, it is so cool, urban, artsy, and sophisticated. Just my two cents. I don't personally know anything specifically related to tanning affecting breastmilk. However, I would think anything that causes chemical changes in your body (causing your skin cells to produce melanin) might not be a good idea because who knows what other cells could start to mutate, and it doesn't seem unrealistic that it would affect breast milk, even if the scientists haven't discovered it yet. I will add one more thing, because I am so serious about preventing skin cancer and sun damage - my mom is in her mid-sixties and has stayed out of sun exposure her entire life - sunblock, big floppy hats, long-sleeved shirts if she's gardening or at the beach, etc. And her skin looks fantastic! She doesn't look a day over 40, and her friends the same age as her who tanned look like they are their age or older. Just wanted to mention it. I'm not being judgmental, I just wanted it to be something to think about. If I were you, I would opt not to tan and to embrace your natural skin color, just because I wouldn't want to risk anything for my baby. Just like even though they say it's okay to have a glass of wine now and then during pregnancy, I did not do it, just in case. You never know what doctors and scientists will find out down the road, so I'm all about prevention!
