Do the children of the maternal aunt whom the mother breastfed become maharim to the children of the wet nurse, knowing that the mother does not recall the number of nursings, but she felt a heat in her breast during breastfeeding?

Your mother becomes a foster mother to your paternal aunt if she breastfed her five times within two years of age, before weaning. A recognized suckling is when the infant takes the breast and drinks until he leaves it willingly. If your mother remembers that she breastfed her five times, then your paternal aunt is your foster sister, and her children are your mahrams. However, if your mother is doubtful about the number of sucklings, the prohibition is not established, and your paternal aunt's children are not considered your mahrams.
