I think it's fine too. The recommendation is no more then 2 cups a day. I switched to half and half and drank 2 cups throughout. We still need that "get up and go".
I think you'll be OK! 5 cups would be an excess but 2 cups sounds OK to me.
For my pregnancy I started with no coffee... then I was too tired and drank 1 cup/day + a lot of chocolate lol!
I've never been a coffee drinker, but I LOVE caffeinated diet soda. I cut that out more because of the chemical stuff than the caffeine. I've been told the same--keep it to 300 mg of less. I do eat some chocolate though, and I know that has caffeine...
I've been having just regular coffee and I dont care for pops & sodas...but I may eat chocolate from time to time ;-)
I don't think 2 cups a day are going to cause any problems. If you would feel better, you could always try the half-caf. I cut down to 1 cup a day but every once in a while i sneak in another afternoon cup. I believe 300mg is the recommended top amount of caffeine, and if you are only having 2 cups and not drinking caffeinated sodas or eating a lot of chocolate or other foods with caffeine you should be within that limit. Just regular coffee though, no capuccinos or espressos...
