She never care for anyone in the family but only MONEY.
The last time I gave birth to my daughter, she told my husband no need to employ maid, just give money to her and she will do the maid's job. I did not believe her so I hired a maid anyway. Then she said to my husband that she will do the 'Pui yuet' for me since my maid don't know how to take care of me after giving birth, my husband paid her $4000 a month to come to my house to take care of me. She came every day, but just watch TV, speak on the phone with her friend, doing exercise at my lounge (she is just over 60) and did nothing for me and my daughter, she even ask me not to carry my daughter but let the maid do it since the maid is getting paid. Because the maid knows nothing, I have to bath for my daughter, feeding my daughter at night, go to market to buy food and boil soup for myself during the first month, I ended up having hormone imbalance and was unable to get pregnant for about 4 years after giving birth to my daughter.
The only thing my 奶奶 did during the first month after I give birth is cooking the 'ginger pork leg', but she did not need to pay anything in cooking since I delivered the vinerger to her home, but she charged me $1000 back for cooking the ginger pork.
Eventhough she is this bad, I did not tell my husband at that time because I don't want to put him in a difficult position, my 奶奶 therefore come around my house a few hours everyday until my daughter is 1.5 years old and getting paid $4000 per month. For the 1.5 year, she never feed a bottle of milk or water to my daughter, never change a nappy and did not even know when my daughter is not feeling well. Eventhually, we found out from the view cam that she taught my maid how to tell lies to me and ignore my daughter while she is at my home but only gossip with the maid about me. My husband was ferious after seeing all this from the view cam and stop her to come to my house any more.
she taught my maid how to tell lies to me, tell my maid to do less work so I will need to do it myself when I got home. Like you said, she is crazy because she is jelous.
So this time I am pregnant, we never tell her becaue there is no point to tell her, she is not helping but only making trouble. I don't know how she will react after I give birth.
