"Baby Girl" entered the
Billboard Hot Country Singles & Tracks chart at number 56 on the chart week of July 24, 2004. The single reached its peak position of number 2 on the chart week of April 2, 2005, a position that it held for two weeks. "Baby Girl" became the highest-charting debut single for a country group since 1991. The single set a new record for the longest chart run since the inception of
Nielsen SoundScan in 1990, spending 46 weeks on the charts. This discrepancy is due to a change on the chart dated January 13, 2001; as part of the chart's reduction from 75 spaces to 60, active songs at the time had their total number of weeks adjusted to count only weeks spent at number 60 or higher, thus reducing the counted number of weeks for "Right Where I Need to Be" from 23 to 16. In the same book, "Baby Girl" is tied with
Diamond Rio's 2002 single "
Beautiful Mess" and
Carrie Underwood's "
Before He Cheats" as the second-longest chart run in this era, Underwood's chart run having come in 2006 and 2007. }
