Does Brushing Teeth Takes An Hour?

Why don't u also step into your bathroom for taking bath n take ur own time? Or offer to help your co sis in getting her kids ready while she does cooking for a change!
Are you working? If not, get a job as soon as possible and get busy with it.

 

Brushing teeth definitely won't take that long. But having 2 kids, no matter how big they are, will take some times out of the kitchen... Either to supervise them, groom them or even to instruct them specially when they are ready to School, eating time, study time etc...

However, it doesn't mean you must work all the chores while she is around, pretending to be busy.

If I were you, I too would do my personal chores when she is not around the kitchen. I would brush, bath, iron and do my works and pretend to be busy on something else like helping H.
But then, I would join her back as soon as she is in the kitchen for cooking. This way, both can share the kitchen chores, and the cooking will be done in 30 min-1 hr.

 

What if she announces?
Why are you so worried about her announcements as long as you are sure that you took time off for something important.
Defend yourself saying the actual reason.
Accept it wholeheartedly that you have taken time off.
Your life is not dedicated to your in laws' kitchen. There is something more than that.
First of all, accept this, and react.

 

Guess its better you share your works, you do breakfast n dinner and let her do lunch
Or you do cooking n let her do washing so that she can t escape
No sharing same works, now only different works
You can casually say" my dearest co sis , I 'll take care of break fast, you do dinner, now you take rest"
This might solve the problem

 

@kaveriudy...Just gather yourself and go get a job! That is the only way.... for I have seen a situation like this to one of my family members, her co -sis-in-law was just like yours. Now that sis-in-law is into her 50+ yrs , still the same. These in-laws also never accept and stay the same till they leave the earth.
My relative often repents for not taking a job and now it is too late for her.

 

Ignore if your MIL makes faces. Pretend as if you have not noticed her.
If there is a family rule, which is so common in your culture like serving others, cooking only by DILs, then I wouldn't break that for no reason.
But it doesn't mean cooking 24/7 and serving as if you are brought to that family for this sole reason.

If there is a common expectation, you must figure out how your co-sis is in the good books of MIL though she doesn't follow this norm?

I think the problem is more of your own insecurity, low self esteem and fear as a new bride. That's why you are way too much bothering about pleasing people.
Blame your family or upbringing...
But that's not the issue now.

Just ignore and don't care about other's reactions. But do what is reasonable.
