Like "Diabetes in a child is the same as diabetes in an adult. What is much more important is this, a diabetic baby \ child is still growing, as in the case of your sister, and their bodies as well as their immune system is still developing. It is very important to be very careful and observant to be on the lookout for changes in the child that may indicate that something is wrong, changes in behavior, attitude, complexion, body temperature can indicate things such as sickness, allergic reaction, infections etc. You need a general understanding of diabetes, what it is, what it does and what you can do concerning it. Please be very careful and protective of your baby sister, she cannot do for, or take care of herself, inform and\ or discuss anything that you may see or hear with your parents, no matter how small you may think that it is, everything is important !
