Getting married to have children

Q: Our Prophet (Sallallahu Alayhi Wasallam) married many women time to time. Now my question is: Did he ever marry any woman with intention of having children (as his sons passed away young). Similarly, is there any other Prophet ever that married particularly to have children when one's wife couldn't have children?

Arranging a lift club for school rounds while one is out in jamaat

Q: I have received advice already about not allowing my wife to drive. I have been since fetching and dropping off kids from school myself. However at present I am away in jamaat and return in a few weeks. My wife is very afraid and protective to send our young kids with anyone or a lift club and her relationship with family is not such where she can inconvenience them to help as they are also busy. Is it allowed for her to fetch and drop off while I am away or am I supposed to leave jamaat and return home.

Also is it ok for me to be in jamaat while she is alone?

How to feel positive

Q: I am pregnant. I Am happy Alhamdulillaah but also I feel very low at times. Maybe because of my rising hormones. My husband is really caring, still I expect more from him. Please suggest me how to feel better and positive. I do offer my prayers. I pray too but negativity is surrounding me. I was a very positive person. Please help.
