I am sorry to hear you little babies are having problems with kidney reflux, my DD has a horseshoe kidney and suffers from kidney reflux.

She was on Bactrim from birth and I weaned her at about 9 months of age as she still had no problems with infection and also as I did not like the thought of her being on these meds for so long, (the Dr had told me that it is recommended to be on the meds until 12 months however if there have been no problems with infections then you can stop as early as 6 months) my DD still has never had an infection. The lastest scan shows there is some scarring as a result of the reflux however we do not need to go back for another reflux/xray test (sorry DD has had so many tests I forget all of the names) until December so I am really happy.

Sorry I am not much help to you, but I thought I would pop in and say hello.
