Difficult question: Smaller body weight and size may be appropriate for your baby depending on many factors. There is a wide range of normal over the first year and the pattern of growth rather than the size is used to decide if this is healthy.Your doc can use a standard growth chart to position weight/length and head size at various points since birth. If normal, relax, if not find out why and work to fix it.
