My mil is Super Super annoying. She is very Ott. I just had a baby and she still expect me to fill up her tea cup all night Long and also serve her all night. If the tea cup is 3/4 full like this picture she will be black face all night and next time she speak to my Husband she will complain. Anyone else mil like this? How to make her understand that I am not her maid.

You have to and should be strong enough to be firm about this with your husband. Say you can not go along with whatever your mil expects. If you are firm......and not flexible, then only he will understand the gravity of your situation. And if mil still continues this way....then I see no other alternative than saying it firmly to mil directly. Please do not be afraid. Always remember you have a right to rest and a stress free life, especially with a baby.
