The study's hypothesis is LMX4 cream, a topical anesthetic cream, will reduce the pain of infants undergoing Lumbar Puncture (spinal tap).
Pain of infants will be measured using the Neonatal Facial Coding System by videotaping the infant's face while they undergo the procedure. A comparison between the group that received active drug and the group that received placebo will allow a measurement of the difference, if any, of the pain experienced during the procedure of the infants.
