Hi welcome to HCM. You must understand that liver is the chemical factory of the body that processes all that we eat. So if it is affected, we must reduce its work load by eating very small amounts at a time, more frequently. We must also eat foods that are easily digested, and give the liver plenty of sugar so that it does not have to work to produce sugar from the glycogen stored within it. So give your daughter very small frequent non oily meals, and more of fruits and sweetened juices till she is better.
