If you do not tune her properly, you are going to suffer a lot. This is just the first month...
1. No need to care about what she likes/dislikes to eat, just eat whatever your family eats
2. Ask her to bath at a particular time
3. Ask her to do ALL the household chores in front of you for a consecutive 5-7 days, when she washes toilet, you can stand inside bathtub and watch.
4. Explain to her she will take care of all the bathing and babycare duties after you go back to work. At the meanwhile, STAND and WATCH you.
5. I keep my maid's mobile phone during weekdays, I only give it back to her on Saturday late evening for charging battery. NO mobile phone during weekdays. --> If you don't stop her now, you will be regret... she will TALK and TALK non-stop whole day. Then later you will receive letter from telecom companies to ask for money. She will tell you "I want to borrow money to settle fees". Then you will give, because you have been so used to her problems...
