My domestic helper has been with me for almost 8 months. We have been constantly reminding her the importance of cleanliness and hygiene, more so since one of my kid has eczema. Yet it seems to fall on deaf ears as she just apologises every time we catch her lack of hygiene. She will "try" to be hygienic for the next time and after that goes back to her ways until we catch her again. This cat and mouse game is getting very tiring. Any suggestions on how to make her remember the importance of hygiene?
