Kee chang means: Singaporean term for zongzi - the sticky rice dumplings wrapped in bamboo leaves that are traditionally eaten during the Dragon Boat Festival. In Singaporean Hokkien, kee chang refers specifically. It is mainly Singaporean English and may not be understood outside that context. There is no real cause for parental concern; it is descriptive vocabulary rather than risky behaviour. This is a food-related word and harmless in itself.
