Yep! I look forward to my 1-2 cups every morning! Most babies do fine with mom having a couple of cups a day. Some babies are extra sensitive to it, but most are not.
Milk levels of caffeine are quite low (0.06-1.5% of maternal dose) and usually peak 1 hour after ingestion.
Babies whose mothers avoided caffeine completely during pregnancy seem to react more to caffeine in mom's diet. Even if baby is sensitive to the caffeine now, he may not be when he's a little older -- so if you do have to stop or limit your caffeine intake, you can try again when baby is older.
Also, there is no evidence that caffeine decreases milk supply. The myth that caffeine will decrease milk supply is widespread. Many moms consume caffeine, and it ought to be easy to document any adverse effects of caffeine on milk supply. No such effect has been observed, however, despite a number of studies.
