What is the ruling for continuing to breastfeed a child after becoming pregnant? Is it permissible to continue or should the child be weaned immediately?
Bismihi ta'ala
As long as the infant child you are currently breastfeeding has not reached the age of weaning, then there is no shar'i problem in continuing to breastfeed the baby.
Of course, you should consult your doctor and ask if continuing to breastfeed while pregnant will make you weak, or bring about any other problems.
And Allah knows best.
