Really need some help...

Ok...here's the long story told in the shortest way possible.  DD was born at 6lbs 2oz.  The next day, her billi levels were up when she was born I was basically forced by the hospital doctor to start giving her formula.   If I had only known everything about BFing that I know now.  This put us off to a very slow start and for the next 2 months we struggled and struggled to get my supply up and end the supplementing.  I had to go back to work after 5 weeks which made BFing that much more of a challenge but I was determined.  At her 2 month well check, DD weighed in at 9lbs 3oz.  Our pediatrician said her weight gain was acceptable and everything was progressing fine.  Right around this point, I finally got to the point where I could take her off the formula for the most part.  She was EBF when she was with me, and while I was at work she was given whatever milk I had pumped the day before and usually 1 - 2 bottles of formula.  ( I still have trouble pumping enough to sustain her while I'm working).  Developmentally, she is bright and happy, full of personality and hitting all the milestones ahead of schedule. 

Two weeks ago, we had to take DD to the pediatrician with an unexplained fever (101 degrees).  When we arrived at the office, LO weighed in at 9lbs 3oz, the exact weight she was 7 weeks prior at her 2 month well check.  We were immediately sent to the ER, so that they could test for a UTI (as the source of the fever) and do blood work to try and find out why she wasn't gaining weight.  I tried to explain to my pediatrician and also the ER doctor that I felt like she had lost weight lately, and had suspected that it was caused by whatever was causing the fever, along with the fact that she seemed dehydrated...but no one seemed to listen.  I know that DD was slow gaining weight anyway, she was very long and very lean, but I also know that she had gained since that 2 month visit.  I remembered putting her in the tub and my husband and I talking about the chubby belly she was getting.  After a night in the ER, nurses attempting to draw blood from my 4 month old on three different occasions, and 15 minutes of what seemed like a very inexperienced nurse trying to insert a cath into DD unsuccessfully while she screamed in pain, I was just done.  The nurses came in later to inform us that none of the blood that was drawn previously was usable, and we needed to do it all over again.  I said that I was taking DD home and would take care of everything the next day during business hours.  LO had been through enough at this point, and NO ONE had even checked her fever since we had arrived at the ER!  At this point, the pediatrician on call at the hospital FINALLY came down to see us.  She informed us that we needed to immediately start supplementing DD with formula, as much as she would drink, to get weight on her.  She didn't even seem that concerned with the cause of the fever...only the fact that she believed my BFing efforts were proving unsuccessful. 

The next day I followed up with my pediatrician.  DD weighed in that afternoon at 9lbs 8oz, she had already gained 5 oz in less than 24 hours.  The cultures at the hospital ended up showing that she did have a UTI.  But, with regards to the weight issue, our pediatrician told me to supplement, supplement, supplement. I tried to explain DD had been getting 8 - 10 wet diapers and around 2 BM per day.  I explained she was not fussy, STTN most of the time for at least 5 or 6 hours, burping well after nursing, etc, etc.  I explained again that I felt like she had lost weight and asked if the UTI could cause that, but never got an answer...just told to supplement and then come back the next day for another weigh in. The next day, DD weighed in at 9lbs 14oz, which added up to her gaining 11 ounces in just 48 hours.

 So, I kept supplementing.  The first few days I gave her as much as she would drink. . . and she was lathargic and miserable.  She did not want to play, did not want to sleep, she was just bloated miserable.  Even the babysitter said she seemed sluggish and thought there was just too much going in.  5 days later at another weigh in, she was up to 10lbs 5oz, for a total gain of 1lbs and 2 ounces within a week. Everyone at the doctor's office acted pleased, about how they were so surprised she'd gained so much...when I'm there looking at my usually BF little girl looking completely miserable.  She was up to 16 - 20 wet diapers per day and tons of poopy ones.  Her butt was on fire from all the wet diapers.  I tried to talk about BFing, but I was told there must not have been enough calories in my milk and to keep doing what I was doing.  My milk supply had dwindled drastically, since my poor girl didn't even want to think about nursing...she was stuffed!

Over the past week, I've been able to get a hold of my LC and talk to some very helpful people from LLL.  They were puzzled at the situation, but also very disappointed that both pediatricians did not offer any support for my BFing.  I have taken matters into my own hands, and started decreasing the formula and trying to get my supply back up.  LO still looks chubby and seems much happier when she gets less formula and more breast milk.  We are supposed to go back for another weight check in a few days.  In the meantime, I'm trying to get an appt with another pediatrician that was recommended by some BFing friends.  I just feel like I was told to fill her full of formula way too quickly.  After doing some research on my own, I've also found out that UTI's in infants can inhibit weight gain and can even cause weight loss.  Why didn't anyone take the time to check that out before shoving the bottle down my babies throat?  I'm just so discouraged...I've tried so hard to EBF...I feel like we were almost there...only to have all of this happen.  Any advice or input would be appreciated
