Weaning of the child due to pregnancy

Q: I have a one year five month old son who eats solids and drinks breast milk at times. I want to wean him off from breast feeding as I am three months pregnant but my husband insists that I feed him until he is two years. I know the weaning period is two years but in this case I would just like to know the masala. Do I need to breast feed for full two years or will I be sinful if I wean him off now?

Performing Salaah in a car

Q: My wife and I do a lot of travelling by car. A lot of times the distances we drive are over 90km. Due to this, sometimes we have to pray on the side of the road or in a parking lot. If my wife prays outside the car like me, there are many people (men and women) who walk and drive by and could see her. In this case, is it permissible for my wife to pray sitting down in the car?
