How can I win my saasu maas heart?

Lollllllllllllllllll ....That was too funny ..
I dont think you can change MILs ....
Just respect her because she is your hubby's mom but don't let her effect your life and your kids life. If she doesnt like daughters, tell her to get sex change surgery herself first :)
In rishto main some times loog kabhi khush nahi hotay chahay app apni jaan day do ....so try hi nah karoo...You are who you are and if her mind cant accept you that way then she needs a brain surgery too.
Also its not only your kids ...its her son's kids too. So if she can talk about her own grand kids like that then app kyo kuch acha expect karti hoo.
