The results of these tests can tell you what to expect as your baby grows into childhood. If you do not know what is causing your baby's slow growth, talk to your baby's doctor about sending specific testing for a virus called CMV (cytomegalovirus) or a genetic test. Your baby's doctor will be able to tell you what testing is the most appropriate for your baby.
