Thanks for your query.Based on the facts that you have posted it appears that your 10 months old daughter is getting repeated episodes of UTI.and her liver
UTI has no relation with enlarged liver.
In view of she getting repeated attacks of UTI it will be better if you consult qualified Urologist
and get following tests done
1) Urine routine and culture.
scanning of the abdomen
3) IVP and MCU to rule out Vesico Ureteric Reflux.
Further treatment will depend on findings of these tests and final diagnosis.
