Call doctor if baby is less than 6 months old or if there's ear discharge. For pain, can give acetaminophen to infants 6 months and younger; acetaminophen or ibuprofen to children 6 months and older.
[added from my comment: According to Baseball Reference, Michael Jordan was 31 when he played one season as an outfielder for the Birmingham Barons, which were a AA minor league affiliate of the Chicago White Sox. (for context, AA is the second-highest minor league level; AAA is the only step between AA and the Major League).
What's often lost in this narrative, however, is that Jordan and James were actually the same age when they were crowned NBA champions for the first time. After three seasons under Dean Smith as a member of the North Carolina Tar Heels, Jordan was 27 years old in 1991 when he won his first NBA title. By the time he turned 34, Jordan had won six championships for the Chicago Bulls before retiring for a second time in 1998.
