Breastfeeding

Child being fed with porridge made from breast milk

Q: Porridge was made from breast milk of a certain woman and another child (under 2 yrs) happened to eat that same porridge. The second baby who the porridge was not meant for, ate 2 spoonfuls of it before they realized that there was breast milk inside. 

So, another Mufti was saying that because the milk hasn't come directly from the source, so the maslah of Rada'at doesn't apply. I just wanted to confirm, will Rada'at be established and will they be considered siblings or not? 

Details of the Porridge: 

Porridge is rice porridge, which is in powder form 
It was 3 tablespoons of powder mixed with 60-70 ml of breast milk and 2 drops of honey 
It was then put into the fridge 
Later on, to thin it out, just over a teaspoon of boiling water was put in. 

The porridge was not put on the stove

Woman breastfeeding openly

Q: I wanted advice on how to deal with a situation with my aunt (mothers sister). 

A lot of times she breastfeeds very openly (breasts fully uncovered) in front of my brother who is 14 years old. The other day I told her that if she needs to breastfeed then she should go into another room or at least throw on a blanket and she got angry at me and said that it’s comfortable for her and her baby to breastfeed the way she does. 

My mother found out about this and said that I should respect my aunt and that it was fine for her to breastfeed like that since my brother is her nephew. Am I in the wrong?

Breastfeeding while pregnant

Q: I have a one and a half year old daughter and my intention was to breastfeed her till she reaches the age of 2 as per the Islamic ruling.

However I have just found out that I am pregnant again, Alhamdulillah.

My question is: is it permissible for me to continue breastfeeding while pregnant, or is it advisable to stop asap?
