The suggestion that IR emission lines from pre-main-sequence stars of relatively low mass originate in primarily neutral winds is examined. In particular, predictions of the Br-alpha line emission for a range of mass loss rates are presented and compared to observations. The low Br-alpha emission for a given mass-loss rate indicated by the observations can be explained if the winds are cool (7000 K, in most cases) and, consequently, primarily neutral. Because the Br-alpha emission is a strong function of both the wind and stellar temperatures, it cannot be used to derive mass-loss rates for these cool stars; but, when used in conjunction with other data, it can provide strong constraints on mechanisms for driving the stellar winds and molecular outflows.
