caffeine and breastfeeding.

Kimberly
Just wondering how much and what kind of caffeine (if any) breast feeding mamas have a day. While I was pregnant my doc was cool with me havin a cup of coffee a day. (I would just have half caff most of the time). I would love to have a little more coffee during the day. Most research I found reports staying under 200-300mgs. Some more. I wanted to hear from real moms and not statistics? Thanks ladies!
