If you have a young child, and then you pregnant again, if you don't let the maid know you will have one more helper, they will resign already because they don't want to take care 1child + 1 newborn. My maid started worry about this since she came last year sept. I have a 3yr old girl, and she always worry I will have 1more child. I can see she is not concentrate on her work. After I told her I will hire 1more maid if I am pregnant, now she is happier and not so lazy and not making soooooo many mistake. Big difference.
