My family is planning for a holiday to Hong Kong. Should I bring my helper along? If not, where can I put her for the time we are overseas?

If you & your husband can handle your children without helper, I'll suggest that you don't bring helper along. Firstly, family time is precious and I think family can bond better without a 3rd party.Secondly, you can save money from not purchasing ️additional flight ticket. You can place your helper with your parents or in laws.
