Domestic Helpers Child

To enter HK,the child would have to have a dependent visa. As far as I know a domestic helper cannot have a dependent visa issued under a domestic helper visa. If the father is a HK person, the child was born in HK, then this of course would make a big difference. The father would need to apply for the child's visa as a citizen or permanent resident, but not the mother if the only visa the mother has to live here is a domestic helper visa.
