Breastfeeding

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?

Period of breastfeeding

Q: A hadith states لا رضاغ بعد الفصال

Hidaya mentions that the growth from the milk stops after the child's nutrition is changed. If a child was weaned at 8 months due to a 2nd pregnancy, then the mother gave birth and is feeding the 2nd child, can she feed the first child expressed milk?

The child is already weaned, drinking goats milk in abundance. Mothers milk will definitely be more nutritious, but does the hadith mean that it will be prohibited to feed the child who was previously weaned even though it is less than 2 years old ?
