More formula woes

I am really wishing that nursing had worked for both Mom and Ben - we are beside ourselves trying to find a formula that will work for this little guy. Good Start did not agree with Ben at all. 48 hours later, he is even more fussy when his tummy hurts and he has not slept more than an hour (we were blessed with three hour naps before). We are onto a Soy based formula by Enfamil and some Levsin (Rx) drops to help when needed (they are usually used for colic). Say a prayer that the soy formula and/or the drops help. We don't want to keep experimenting with his little system. Aunt Bonny and Amelia came in last night to give us some relief - both Jeff and I had a full night's sleep! SUCH a blessing.
