If a baby is low in weight but has a normal length and head size, the baby will usually catch up in growth over the next few months or years. If the baby is small because both parents are small, the child will continue to be small like the parents. If the baby is also short in length and has a small head size, there may be some catch up, but usually growth will remain less than normal and the child will be smaller than expected for the family. This too, depends on the severity and cause of the growth problem. If a baby is low in weight but has a normal length and head size, the baby usually develops normally although some have difficulty in school, especially with math and reading.
