Male infants are routinely given a sweet solution prior to circumcision for analgesia.
Michelis and Hoyle recently published a great review of the possible use of sweet solutions in the ED for pediatric patients.
Pediatric patients often undergo painful, but rather routine procedures in the ED such as IV and urinary catheter placement, venipuncture, and lumbar punctures.
More often than not, however, they are not provided analgesia prior to these procedures.
It is believed that repetitive early pain events lead to anxiety and other behavioral disorders while also decreasing pain tolerance.
In children less than 12 months, consider giving a sweet solution (2mL of 24% sucrose) 2 minutes before any painful procedure.
Multiple studies indicate decreased pain as measured by significantly reduced crying times.
It's cheap, safe, and works!
