Doing aqeeqah for one's family

Q:

1. I want to know that I have a son that is 11 months. I want to do my, my wifes and my sons aqiqah on the same day. Is it possible because I don't know if my aqiqah was done or not because in our family aqiqah is mostly done on the occasion of marriage.

2. Also, give me details about how I do and what to do on the occasion of aqiqah so that we are safe from unwanted thing.s

3. And also I want to know, does me and my wife have to give silver equal to the hair in charity or can I pay the same price in cash? 

Gaining knowledge of the development of the fetus through a scan

Q: As we recite the Holy Quraan and we see in Surat e Luqman that some kind of knowledge is with Allah and no one knows about that. For example when will it rain and what is inside of the women, either male or female and when and where will the person die. So nowadays we see the technology that every one knows that what is inside a female's abdomen. So is there controversial that the new tafseer will change from the old one and what answer will we give to non muslims when we explain these ayaats.

Husband typing in a draft message "you go" without the intention of divorce

Husband not allowing children to visit their non-Muslim grand-mother

Q: I am a revert alhumdulilah. I am in a dilemma regarding visiting my mother who is Hindu. My husband does not allow my kids to visit her because she has a temple in her yard. It's not like the kids play outside. My family has a lot of respect that I am a Muslim and they have never forced us into doing anything unlawful or haram. My mother is now heartbroken as she can't be with her grandchildren and I feel bad visiting her without the kids. Her tears are haunting me. I know that a mother holds Jannat under her feet and to make a mother cry is the biggest sin. I can't take this anymore I'm miserable and how do I earn Jannat one day in sha Allah if my mother is hurt. So please advise as I can't hear or see my mother cry anymore.
