I hear 'no' from some sources, but 'yes' from others. (And if no . . . why not?) Sidebar: I also heard regular and even decaf coffee is bad for the baby. Can you shed some light on this for me? At work the other day, a VERY pregnant customer orders a venti iced coffee. The person on the register really wants to ask, "Um, are you SURE you don't want decaf?" But, of course, you can't do that. So he just said, "Regular or decaf?" She said regular but then she reassured us it wasn't for her.
