If the baby is getting better i would not add another med, to much meds can overload a bird with chemicals and with sulmet you have already gotten rid of the bad things in the gut but you have also gotten rid of the good gut floral the baby need to stay healthy.
Was the baby diagnosed by a vet? sorry i did not read it if it was.
