拜拜 is not considered childish, but is more casual than other forms of good-bye. It can be use on children / friends / even seniors, but should not be use for Clients / business partner / etc.
拜拜 is not casualness and/or childishness,it is a more friendly way to express goodbye ,and majority use between people who have good relation,or see somebody for the first time and build a friendship each other. So does it in Taiwan I think:)
