How long does it take a premature baby to catch up to a term baby?
Catch up growth generally occurs in the first 2 to 3 years of life. The smallest of premature babies may take longer to catch up. It may take anywhere from 8 years through adolescence to reach their full growth potential. Some babies who were born premature do not ever catch up and may have developmental and learning disabilities or serious health problems for the rest of their lives.
