Jazak Allah to everyone for ur lovely comments.

I love that Dua!!

“My Lord, have mercy on them, as they did care for me when I was young.”

By Positive encouragement. You daughter said the above sentence because she thinks she never did anything right,.. so my advice to you ( as I had the same issue with the same age of my daughter ) take a deep breath, do not react when she says so and calm yourself, now instead saying you are doing this WRONG…………..say, you are trying your best or excellent effort, or hmmmmm you did almost right , would you like me to help you etc,… again positive encouragement. Children make mistakes, sometimes they repeat mistakes, so be patient though I myself is not very good at it but I learned how to deal with my daughter who is 7 in Canada.
Sometimes my daughter gets frustrated by doing something and then not only makes mistakes but also crosses the limit and values that we are trying to instill in her,…. again the same thing I will take a moment, will talk to her by starting all the GREAT and GOODS she has, once she starts feeling that mom is there to help then she focuses, and listens.Hope this tip will help inshaaAllah
