Sorry to say Colorful my mom trained my sisters kids at the age of 3 months and she trained in few days. When she was doing that I said how could that todler understand that she said just watch and see we used to do that.
I was amazed when in few days I saw that toddler was pottying.
MO3. If you wanna achieve gr8 result in each class and later to get gr8 marks by kids and to be selected in extra ordinary kids then yeah you have to teach them ahead of time.
I did this with my brother Yeah he can even find out mistakes in books and got great result and was genius in their peers.
I also trained 1 kid too and yeah he got position in his class and also teaches his classmates everyday over the phone. Yeah you have to IF you want you kid to be extra genius.
Always got appriciation and lots of tareef for the kids. Masha Allah and Alhamdolillah.
