Pregnancy and Parenting

Q:

My first question is: In Islam, when does a child have the right to go outside and maybe socialise or even go to the mosque and come back by themselves. Say a general ruling for maybe a boy who is 13-14 years old.

My second question is: Up to what extent is an older sibling allowed to punish a younger sibling i.e. corporal punishment or verbal? 

My third question is: If your parents say something like "I don't care about what sunnah or fatwah says, it's about what I say! It's about me!" how do you respond in a respectful way.

Q: Where can one find advice/books to guide women during their pregnancy? Most books that I have come across only advise from the time of birth.

Q: I have a question that my wife is pregnant for the second time. We have one more baby Alhamdulillah. In a couple of days, we have seen that we have lost our first child and later we got her in the dream. We want to give Sadaqah of our first child as well as of the baby who is in his/her mother womb. So is it possible that we can give Sadaqah of the child who is supposed to come in Duniya very soon?

Q: Are you allowed to freeze your placenta and eat it or make it into pills and then consume it?

Q: I want to do our istikhara for moving from UK to Pakistan for 4 years time for my kid's good education. Kindly advise me on that please.

Q: I want to know that if a child was expected to do certain things (provide,work etc) for the family by a certain age even when having other responsibilities isn't it only fair to expect all the other children, when they reach that age to be expected to do the same (especially since they have lesser responsibility than the first child did) as in Islam all the children should be treated equally, so just like they will have give driving lessons to the others as they did for the first child the same way the other children should be expected to do the same chores and work for the family the way the first child did.

Q: If someone regularly takes baby for massage with the belief that this will help to strengthen and mold the limbs properly also the molding of the baby's head. Is this okay?

Q: Can someone carry a baby whose hair is yet to be cut?

Q: Is it established anywhere that when a baby is born that the fathers sister needs to give out something? Many times you find people give out sweet platters to family members when a child is born. Is this practiced in Islam or is it just customary?

Q: On the birth of a child some practice a custom of feeding friends etc. some sweet meats, burfi etc for the happy occasion. Is this a part of Deen? Should it be stopped?
