Hi, I am thinking to get a helper. However, I am living in a 3 rooms flat. 1 room for myself, husband and daughter. 1 room for my parents and son who help to take care of my 18 mo son. Any idea how can I squeeze some space for helper?

Move to a bigger unit or put 18mo son in CC then just engage a part time helper(no need stay-in). You also have to think where the maid is going to keep her stuffs especially her clothes that includes her undergarments bcs that is a very private stuff. Put yourself in her situation lor. Imagine you also a helper having to leave your own family behind to work for another family and they didnt provide you with the most basic stuffs that includes your privacy.
