I am feeling v sianz to go work... :( and I think I got dislike-mil-syndrome.. not tt I dun like her.. at the same time I am grateful for her to take care of my baby but at the same time dislike her presence.. feeling depressed....

It's most important that she's willing to take care of your child for you, so I would suggest that you put up with it. You may need her help more and more in future as your child grows up, so it's best to maintain a good relationship with your MIL. I should add that some family members do change for the better after having a baby in the family.
