Slightly OT.
This drives me insane. babies inherently are NOT lactose intolerent.
Personally, i see no reason to bottle feed on anything other than breastmilk, but thats a whole other debate, but would probably solve this problem.
Soy formula will help with the fussiness, and it takes time for a babies digestive system to get used to something its not qute made to use yet.

Congrats on the new baby!! It will be a rough at first but totally worth it.
I know an EXCELLENT newborn photographer if you need one! *wink wink-nudge nudge*
